consider a system consisting of four resources of the same type that are shared by three threads, each of which needs at most two resources. show that the system is deadlock free.

Note that the magnitude of the resultant active thrust on the wall is 876.69 kN.

To calculate the magnitude of the resultant active thrust on the wall, we need to use Rankine's theory of earth pressure.

Let's assume that the wall height is also 5.4 meters, and the angle of wall friction is zero.

Then, the total active thrust (Q) is given by:

Q = Ka * H * gamma * H/2

Where,

Ka = Active earth pressure coefficient

H = height of the wall

gamma = unit weight of soil

The active earth pressure coefficient can be calculated using the following formula:

Ka = (1 - sin(phi)) / (1 + sin(phi))

Where, phi = angle of shearing resistance of soil

Substituting the given values, we get:

phi = 30 degrees

H = 5.4 meters

gamma = 19.8 kN/m^3

Ka = (1 - sin(30)) / (1 + sin(30)) = 1/3

Q = Ka * H * gamma * H/2 = (1/3) * 5.4 * 19.8 * 5.4/2 = 876.69 kN

Therefore, the magnitude of the resultant active thrust on the wall is 876.69 kN.

The line of action of the resultant active thrust on the wall will be at one-third of the height of the wall from the bottom. Therefore, the line of action of the active thrust will be at a height of 1.8 meters from the bottom of the wall.

Answer:

E = 8.83 kips

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

Now, the modulus of elasticity (E) is given as:

\(E = \frac{\sigma}{\epsilon}\\\\E = \frac{6.62\ kips}{7.5\ x\ 10^{-4}}\)

E = 8.83 kips

Among the DC motors listed, the electrical ratchet mechanism is commonly associated with a stepper motor.

The electrical ratchet mechanism is typically linked with a stepper motor among the available options for DC motors. A stepper motor makes use of electrical pulses to initiate precise rotational movements, thereby enabling accurate control over its operation.

It generally follows a sequential process where each movement is associated with a set rotation angle. The stepper motor shares a quality with an electrical ratchet as it moves forward in specific intervals, reminiscent of the ratcheting action.

The ratchet-like behavior isn't inherent in other forms of DC motors like brushless DC motors and brushed DC motors.

Answer:

Let us see different corner cases.

Complexity function T(n) — for all problem where tree traversal is involved — can be defined as:

T(n) = T(k) + T(n – k – 1) + c

Where k is the number of nodes on one side of root and n-k-1 on the other side.

Let’s do an analysis of boundary conditions

Case 1: Skewed tree (One of the subtrees is empty and other subtree is non-empty )

k is 0 in this case.

T(n) = T(0) + T(n-1) + c

T(n) = 2T(0) + T(n-2) + 2c

T(n) = 3T(0) + T(n-3) + 3c

T(n) = 4T(0) + T(n-4) + 4c

Explanation:

The regenerative Rankine cycle has a number of advantages over the simple Rankine cycle, such as Higher thermal efficiency, Lower exhaust, and Smaller physical size, Shorter startup time.

Higher thermal efficiency as the steam is recycled back to the boiler, resulting in higher efficiency and better fuel economy. Lower exhaust steam pressure and temperature, making it more suitable for applications with lower temperature differences between the heat source and the sink. Shorter startup time as the turbine does not require as much steam to reach operating conditions. Smaller physical size, as the high pressure and temperature equipment, is not necessary.

Correct tire pressure is essential for tire wear and vehicle handling. Both technicians are correct. A vehicle's tires are one of the most critical components when it comes to safety and performance. The proper maintenance of tires is critical for both the life of the tire and the safety of the vehicle.

Tire pressure affects vehicle handling and tire wear. Tires underinflated by only a few PSI (pounds per square inch) can cause uneven tire wear and reduced fuel economy. Overinflation can cause excessive wear in the center of the tire and lead to a rough ride.

In addition, incorrect tire pressure can lead to tire failure, which can result in a loss of vehicle control and an accident.Correct tire installation is also essential for safety. Proper tire installation includes mounting and balancing the tire, ensuring the lug nuts are tightened to the manufacturer's specifications and inspecting the tire for damage or wear before installation.

The steel subcontractor will furnish and install the steel angles.

In this scenario, the need for additional reinforcement in the form of steel angles arises due to the absence of rebar trim bars. The rebar subcontractor did not provide additional reinforcing because their work practice is limited to only adding trim bars around deck penetrations physically placed on the deck.

Hence, the responsibility of furnishing and installing the steel angles falls upon the steel subcontractor.

Steel angles are commonly used to reinforce concrete structures and provide additional support. They can be installed by welding or bolting them onto the existing structure. In this case, once the steel angles are installed, the deck will be core drilled for the conduits to pass through.

The error in the array declaration int (5] numbers is option A: it should be int numbers[5].

In C++, the correct syntax for declaring an array is to first specify the data type (in this case, int), followed by the array name (numbers), and then the number of elements enclosed in square brackets (5). The correct syntax ensures that the program can properly allocate memory for the array and access its elements.

Option B is incorrect because spacing has no effect on the program's functionality. Option C is incorrect because there is indeed an error in the declaration. Option D is incorrect because empty square brackets would indicate an array with an unknown size, which is not allowed in C++.

In conclusion, the correct way to declare an array of 5 integers is int numbers[5]. It is important to pay attention to syntax when writing programs to ensure they run correctly.
