Consider the following C program: #include void square(int num) \{ num = num * num; \} int main() \{ int x=4; square (x); printf("\%d\n", x); return 0
i
\} This program currently prints out " 4 ." If you wish, compile and run the code to confirm this fact. In the current code, x is passed by value to the square function. Modify the program to use pointers and addresses so that x is passed by reference instead (and is squared as a result). Your solution should not make the square function return a value.
To modify the program to pass the variable `x` by reference using pointers, we need to change the `square` function to take a pointer parameter.
By dereferencing the pointer and updating the value at the memory address it points to, we can modify the original variable `x`. This ensures that `x` is squared within the `square` function.
Modified code:
```c
#include <stdio.h>
void square(int* num) {
*num = (*num) * (*num);
}
int main() {
int x = 4;
square(&x);
printf("%d\n", x);
return 0;
}
```
In the modified code, the `square` function is modified to take an `int*` parameter instead of an `int` parameter. This indicates that it expects a pointer to an integer. Inside the function, we dereference the pointer using the `*` operator and perform the square operation on the value it points to. This updates the original variable `x` in the `main` function.
In the `main` function, when calling `square`, we pass the address of `x` using the `&` operator. This allows the `square` function to directly modify the value of `x` at that memory address.
As a result, when we print the value of `x` after calling `square`, it will be the squared value (16 in this case) instead of the original value (4).

in the same circuit if w/l of the transistor is set so that the transistor drain current is 3 ma, what rd value keeps the transistor at the edge of the ohmic region?
To keep the transistor at the edge of the ohmic region, the value of RD is calculated using Ohm's law, which states that current is equal to voltage divided by resistance.The equation that determines the RD value of a transistor in saturation mode is the following:
RD = (VDSQ - VDSsat)/ IDQ, where VDSQ is the DC voltage between the drain and the source terminals, VDSsat is the saturation voltage, IDQ is the DC current flowing through the transistor, and RD is the resistor connected to the drain terminal that limits the current through the transistor.In this case, the transistor's drain current is set at 3 mA, which is equal to the IDQ value. Therefore, the equation becomes:
RD = (VDSQ - VDSsat)/3 mAIf we assume that the transistor is operating in the ohmic region, then VDSQ is the supply voltage VDD, and VDSsat is zero. Thus, the equation simplifies to:RD = VDD/3 mAIf we set the drain current at 3 mA and assume that the transistor is operating in the ohmic region, then the RD value that keeps the transistor at the edge of the ohmic region is VDD/3 mA. This value depends on the supply voltage VDD and the physical properties of the transistor. The transistor's W/L ratio can be adjusted to achieve the desired value of IDQ and the corresponding RD value.

A ductile hot-rolled steel bar has a minimum yield strength in tension and compression of 350 MPa. Using the distortion-energy and maximum-shear-stress theories, determine the factors of safety for the following plane stress states.
a. σx = 94 MPa, and τxy = -75 MPa
b. σx = 110 MPa, σy = 100 MPa
c. σx = 90 MPa, σy = 20 MPa, τxy =−20 MPa
Answer:
Explanation:
From the given question:
Using the distortion energy theory to determine the factors of safety FOS can be expressed by the relation:
\(\dfrac{Syt}{FOS}= \sqrt{ \sigma x^2+\sigma y^2-\sigma x \sigma y+3 \tau_{xy^2}}\)
where; syt = strength in tension and compression = 350 MPa
The maximum shear stress theory can be expressed as:
\(\tau_{max} = \dfrac{Syt}{2FOS}\)
where;
\(\tau_{max} =\sqrt{ (\dfrac{\sigma x-\sigma y}{2})^2+ \tau _{xy^2\)
a. Using distortion - energy theory formula:
\(\dfrac{350}{FOS}= \sqrt{94^2+0^2-94*0+3 (-75)^2}}\)
\(\dfrac{350}{FOS}=160.35\)
\({FOS}=\dfrac{350}{160.35}\)
FOS = 2.183
USing the maximum-shear stress theory;
\(\dfrac{350}{2 FOS} =\sqrt{ (\dfrac{94-0}{2})^2+ (-75)^2\)
\(\dfrac{350}{2 FOS} =88.51\)
\(\dfrac{350}{ FOS} =2 \times 88.51\)
\({ FOS} =\dfrac{350}{2 \times 88.51}\)
FOS = 1.977
b. σx = 110 MPa, σy = 100 MPa
Using distortion - energy theory formula:
\(\dfrac{350}{FOS}= \sqrt{ 110^2+100^2-110*100+3(0)^2}\)
\(\dfrac{350}{FOS}= \sqrt{ 12100+10000-11000\)
\(\dfrac{350}{FOS}=105.3565\)
\(FOS=\dfrac{350}{105.3565}\)
FOS =3.322
USing the maximum-shear stress theory;
\(\dfrac{350}{2 FOS} =\sqrt{ (\dfrac{110-100}{2})^2+ (0)^2\)
\(\dfrac{350}{2 FOS} ={ (\dfrac{110-100}{2})^2\)
\(\dfrac{350}{2 FOS} =25\)
FOS = 350/2×25
FOS = 350/50
FOS = 70
c. σx = 90 MPa, σy = 20 MPa, τxy =−20 MPa
Using distortion- energy theory formula:
\(\dfrac{350}{FOS}= \sqrt{ 90^2+20^2-90*20+3(-20)^2}\)
\(\dfrac{350}{FOS}= \sqrt{ 8100+400-1800+1200}\)
\(\dfrac{350}{FOS}= 88.88\)
FOS = 350/88.88
FOS = 3.939
USing the maximum-shear stress theory;
\(\dfrac{350}{2 FOS} =\sqrt{ (\dfrac{90-20}{2})^2+ (-20)^2\)
\(\dfrac{350}{2 FOS} =\sqrt{ (35)^2+ (-20)^2\)
\(\dfrac{350}{2 FOS} =\sqrt{ 1225+ 400\)
\(\dfrac{350}{2 FOS} =40.31\)
\(FOS} =\dfrac{350}{2*40.31}\)
FOS = 4.341
a building foundation made up of a base of poured concrete where finished flooring is installed on top of the cured concrete is best described as
The supporting load-bearing components of the structure will rest on footings that make up a slab on grade foundation. Concrete slabs are poured for the remaining portion of the ground floor. The entire finished flooring is put in place immediately on top of the concrete slab.
Modern structures frequently use concrete slabs as structural support for their flat, horizontal surfaces. While thinner mud slabs may be used for outside paving, steel-reinforced slabs, typically between 100 and 500 mm thick, are most frequently utilized to construct floors and ceilings (see below). The ground floor of many residential and commercial buildings is constructed from a large concrete slab that is either supported by foundations or rests directly on the subsoil. These slabs are often categorized as suspended or ground-bearing. If a slab rests directly on the foundation, it is considered to be ground-bearing; otherwise, it is suspended. There are numerous typical slab designs for multi-story structures (see "Design" for more types): Applications for beam and block, also known as rib and block, are mostly found in residential and commercial settings. Pre-stressed beams and hollow blocks make up this sort of slab, which is temporarily supported until it sets, usually after 21 days. A precast hollow core slab that is crane-installed on the job site. Thinner, pre-cast concrete slabs are strung between the steel frames of high rise buildings and skyscrapers to create the floors and ceilings on each level.

The mass fraction of steam that condenses at the turbine exit is 9%. when A simple ideal Rankine cycle operates between the pressure limits of 10 kPa and 5 MPa, with a turbine inlet temperature of 600°C.
Based on the given information, the simple ideal Rankine cycle operates between the pressure limits of 10 kPa and 5 MPa with a turbine inlet temperature of 600°C. The mass fraction of steam that condenses at the turbine exit can be calculated using the following formula:
mass fraction of condensed steam = (h3 - h4s) / (h1 - h4s)
where h3 is the enthalpy at the turbine inlet, h4s is the enthalpy at the turbine exit if there is no moisture in the steam, and h1 is the enthalpy at the boiler inlet.
Assuming that the steam is initially dry and saturated at the boiler inlet, we can use steam tables to find the enthalpy values:
h1 = hf at 10 kPa = 191.8 kJ/kg
h3 = hg at 5 MPa = 3135.1 kJ/kg
h4s = hf at 10 kPa = 191.8 kJ/kg (since there is no moisture in the steam at turbine exit)
Substituting these values into the formula, we get:
mass fraction of condensed steam = (3135.1 - 191.8) / (3135.1 - 191.8) = 0.938, or approximately 9.4%

Use equation 11-1 as your starting point. (b) Given the Weibull parameters of example 11-3, the factor by which the catalog rating must be increased if the reliability is to be increased from 0.9 to 0.99.
Answer:
(b) Given the Weibull parameters of example 11-3, the factor by which the catalog rating must be increased if the reliability is to be increased from 0.9 to 0.99.
Equation 11-1: F*L^(1/3) = Constant
Weibull parameters of example 11-3: xo = 0.02 (theta-xo) = 4.439 b = 1.483
Explanation:
(a)The Catalog rating(C)
Bearing life:\(L_1 = L , L_2 = 2L\)
Catalog rating: \(C_1 = C , C_2 = ? ,\)
From given equation bearing life equation,
\(F\times\frac{1}{3} (L_1) = C_1 ...(1) \\\\ F\times\frac{1}{3} (L_2) =C_2...(2)\)
we Dividing eqn (2) with (1)
\(\frac{C_2}{C_1} =\frac{1}{3} (\frac{L_2}{L_1})\\\\ C_2 = C*(\frac{2L}{L})\frac{1}{3} \\\\ C_2 = 1.26 C\)
The Catalog rating increased by factor of 1.26
(b) Reliability Increase from 0.9 to 0.99
\(R_1 = 0.9 , R_2 = 0.99\)
Now calculating life adjustment factor for both value of reliability from Weibull parametres
\(a_1 = x_o + (\theta - x_o){ ln(\frac{1}{R_1} ) }^{\frac{1}{b}}\)
\(= 0.02 + 4.439{ ln(\frac{1}{0.9} ) }^{\frac{1}{1.483}} \\\\ = 0.02 + 4.439( 0.1044 )^{0.67}\\\\a_1 = 0.9968\)
Similarly
\(a_2 = x_o + (\theta - x_o){ ln(\frac{1}{R_2} ) }^{\frac{1}{b} }\\\\ = 0.02 + 4.439{ ln(1/0.99) }^{\frac{1}{1.483} }\\\\ = 0.02 + 4.439( 0.0099 )^{0.67}\\\\a_2 = 0.2215\)
Now calculating bearing life for each value
\(L_1 = a_1 * LL_1 = 0.9968LL_2 = a_2 * LL_2 = 0.2215L\)
Now using given ball bearing life equation and dividing each other similar to previous problem
\(\frac{C_2}{C_1} = (\frac{L_2}{L_1} )^{\frac{1}{3} }\\\\ C_2 = C* (\frac{0.2215L }{0.9968L} )^{1/3}\\\\ C_2 = 0.61 C\)
Catalog rating increased by factor of 0.61

Use an anti-seize compound on spark plugs installed in ____________________ cylinder heads.
It is recommended to use an anti-seize compound on spark plugs installed in aluminum cylinder heads.
The anti-seize compound helps to prevent the spark plug from seizing in the cylinder head, which can make it difficult to remove the plug for maintenance or replacement.
This is particularly important for aluminum cylinder heads, as aluminum is a soft metal that is more prone to seizing than other materials. The anti-seize compound creates a barrier between the spark plug and the cylinder head, reducing the risk of corrosion and seizure.
However, it is important to use the compound sparingly and only on the threads of the spark plug, as excess compound can interfere with the electrical conductivity of the plug.
Overall, using an anti-seize compound can help to extend the life of spark plugs and make maintenance easier for those working on aluminum cylinder heads.

Write the code for a DELETE statement that deletes every row in the Vendors table
A) DELETE Vendors;
B) DELETE Vendors WHERE ALL;
C) DELETE * Vendors;
D) none of the above
The correct answer is A) DELETE Vendors;
To delete every row in the Vendors table, we can use the DELETE statement followed by the table name. The syntax for the DELETE statement is as follows:DELETE FROM table_name;
In this case, the table_name is Vendors. So the code for the DELETE statement would be:
DELETE FROM Vendors;
This statement will delete all the rows in the Vendors table.
Option B) DELETE Vendors WHERE ALL; is incorrect because "WHERE ALL" is not a valid syntax for the DELETE statement. The WHERE clause is used to specify a condition for deleting rows, but in this case, we want to delete all rows.
Option C) DELETE * Vendors; is also incorrect because the asterisk (*) is not used in the DELETE statement. The asterisk is used in the SELECT statement to select all columns, but in the DELETE statement, we only need to specify the table name.

The net positive suction head (NPSH) is define as the difference between the total head on the suction side and the pressure head of liquid vapor, velocity, and static. Therefore, the correct option is D- All of the above.
Net positive suction head (NPSH) is a pump industry term that describes the suction side of a centrifugal pump. It is the absolute pressure head, less the vapor pressure, at the pump suction port. The NPSH is defined as the total suction head in feet of liquid absolute, less the vapor pressure in feet absolute. It's also the amount of fluid that a pump needs to function properly. This head must be considered for any pump that is pumping a liquid, and it must be greater than the pump's NPSHr (net positive suction head requirement). It's a measure of the pressure required to keep a fluid from boiling. The most common cause of cavitation is the lack of NPSH. Cavitation is a problem because it generates noise, vibration, and damage to pumps, seals, and impellers.

The statement provided in the question is false. To correctly adjust the sideview mirrors using the BGE (Blind Spot Elimination) setting, the driver does not need to place his/her head against the side window. In fact, the BGE setting is designed to provide a wider and clearer view of the blind spots without the need for the driver to lean or adjust their head position.
To correctly adjust the sideview mirrors using the BGE setting, the driver should first sit in their usual driving position and adjust the sideview mirrors to show a small portion of the side of the car. Then, the driver should activate the BGE setting and adjust the mirrors further outwards until the side of the car is no longer visible in the mirrors.This will provide a wider field of view, allowing the driver to see any vehicles approaching from the blind spot.It is important to note that the BGE setting is not a replacement for proper driving techniques, such as checking blind spots by turning your head and using your mirrors regularly.

A plant engineer wishes to know which of two types of lightbulbs should be used to light a warehouse. The bulbs that are currently used cost $45.90 per bulb and last 14,600 hours before burning out. The new bulb (at $60 per bulb) provides the same amount of light and consumes the same amount of energy, but it lasts twice as long. The labor cost to change a bulb is $16.00. The lights are on 19 hours a day, 365 days a year. (Assume that the firm's marginal tax rate is 40%.) If the firm's MARR is 15%, what is the maximum price (per bulb) the engineer should be willing to pay to switch to the new bulb? Round the service life of the old bulb to the nearest whole number. Click the icon to view the interest factors for discrete compounding when i = 15% per year. The maximum price per new bulb the engineer should be willing to pay is $. (Round to one decimal place.)
The maximum price per bulb the engineer should be willing to pay to switch to the new bulb can be calculated by comparing the costs and benefits over the bulb's service life, considering the firm's MARR (Minimum Acceptable Rate of Return).
How can the engineer determine the maximum price per bulb to switch to the new bulb while considering costs, benefits, and the firm's MARR?1. Calculate the annual cost of using the current bulb:
Annual Cost = Cost per bulb + (Labor cost per bulb * Number of bulb changes per year)
2. Determine the service life of the current bulb (rounded to the nearest whole number) based on the given burnout hours.
3. Calculate the annual cost of using the new bulb:
Annual Cost = Cost per bulb + (Labor cost per bulb * Number of bulb changes per year)
4. Calculate the present value (PV) of the annual cost for both bulbs over their respective service lives, considering the MARR.
5. Compare the PV of the annual costs for both bulbs and identify the maximum price per bulb the engineer should be willing to pay to switch to the new bulb.
By performing the calculations and considering the MARR, the engineer can determine the maximum price per bulb that makes the switch to the new bulb economically feasible.

Compute the volume percent of graphite, VGr, in a 3.2 wt% C cast iron, assuming that all the carbon exists as the graphite phase. Assume densities of 7.9 and 2.3 g/cm3 for ferrite and graphite, respectively.
Answer:
The volume percentage of graphite is 10.197 per cent.
Explanation:
The volume percent of graphite is the ratio of the volume occupied by the graphite phase to the volume occupied by the graphite and ferrite phases. The weight percent in the cast iron is 3.2 wt% (graphite) and 96.8 wt% (ferrite). The volume percentage of graphite is:
\(\%V_{gr} = \frac{V_{gr}}{V_{gr}+V_{fe}} \times 100\,\%\)
Where:
\(V_{gr}\) - Volume occupied by the graphite phase, measured in cubic centimeters.
\(V_{fe}\) - Volume occupied by the graphite phase, measured in cubic centimeters.
The expression is expanded by using the definition of density and subsequently simplified:
\(\%V_{gr} = \frac{\frac{m_{gr}}{\rho_{gr}} }{\frac{m_{gr}}{\rho_{gr}}+\frac{m_{fe}}{\rho_{fe}}}\times 100\,\%\)
Where:
\(m_{fe}\), \(m_{gr}\) - Masses of the ferrite and graphite phases, measured in grams.
\(\rho_{fe}, \rho_{gr}\) - Densities of the ferrite and graphite phases, measured in grams per cubic centimeter.
\(\%V_{gr} = \frac{1}{1+\frac{\frac{m_{fe}}{\rho_{fe}} }{\frac{m_{gr}}{\rho_{gr}} } }\times 100\,\%\)
\(\%V_{gr} = \frac{1}{1 + \left(\frac{\rho_{gr}}{\rho_{fe}} \right)\cdot\left(\frac{m_{fe}}{m_{gr}} \right)} \times 100\,\%\)
If \(\rho_{gr} = 2.3\,\frac{g}{cm^{3}}\), \(\rho_{fe} = 7.9\,\frac{g}{cm^{3}}\), \(m_{gr} = 3.2\,g\) and \(m_{fe} = 96.8\,g\), the volume percentage of graphite is:
\(\%V_{gr} = \frac{1}{1+\left(\frac{2.3\,\frac{g}{cm^{3}} }{7.9\,\frac{g}{cm^{3}} } \right)\cdot \left(\frac{96.8\,g}{3.2\,g} \right)} \times 100\,\%\)
\(\%V_{gr} = 10.197\,\%V\)
The volume percentage of graphite is 10.197 per cent.
Following are the solution to the given points:
\(\to C_{Gr} = 100\\\\ \to C_{\alpha}= 0\)From \(Fe-F_{\frac{e}{3}} c\) diagram.
\(\to W_{\alpha} =\frac{C_{Gr}-C_{o}}{C_{Gr}-C_{\alpha}}\)
\(= \frac{100-3.6}{100-0} \\\\= \frac{100-3.6}{100} \\\\= \frac{96.4}{100} \\\\=0.964\)
Calculating the weight fraction of graphite:
\(\to W_{Gr}=\frac{C_0 - c_d}{C_{Gr} -c_d}\)
\(= \frac{3.6-0}{100-0} \\\\ = \frac{3.6}{100} \\\\= 0.036\)
Calculating the volume percent of graphite:
\(\to V_{Gr}=\frac{\frac{W_{Gr}}{P_{Gr}}}{\frac{w_{\alpha}}{P_{\alpha}}+ \frac{W_{Gr}}{P_{Gr}}}\)
\(=\frac{\frac{0.036}{2.3}}{\frac{0.964}{7.9}+\frac{0.036}{2.3}}\\\\=0.11368 \times 100\%\\\\=11.368\%\)
Therefore, the final answer is "0.964, 0.036, and 11.368%"

Suppose that the function f satisfies the recurrence relation f(n) = 2f(/n) +1 whenever n is a perfect square greater than 1 and f(2) = 1. (a) Find f(16). (b) Find a big-O estimate for f(n).
we can say that f(n) is O(log n). So, to summarize:
(a) f(16) = 7.
b) f(n) is O(log n).
To solve this problem, we can use a technique called recursive substitution.
(a) To find f(16), we can start by applying the recurrence relation:
f(16) = 2f(4) + 1
We can then use the recurrence relation again to find f(4):
f(4) = 2f(2) + 1 = 2(1) + 1 = 3
Substituting this back into our original equation, we get:
f(16) = 2(3) + 1 = 7
Therefore, f(16) = 7.
(b) To find a big-O estimate for f(n), we can use a similar approach. Let's start by assuming that f(n) ≤ cn for some constant c and all n > N, where N is some constant.
Then, using the recurrence relation, we have:
f(n) = 2f(√n) + 1 ≤ 2c√n + 1
We can simplify this by letting m = log₂n, so that n = 2ᵐ. Then:
f(n) ≤ 2c2ᵐ/2 + 1 = 2cm + 1
Since m = log₂n, we have:
f(n) ≤ 2clog₂n + 1
Therefore, we can say that f(n) is O(log n).
So, to summarize:
(a) f(16) = 7.
(b) f(n) is O(log n).
