Properties and characteristics of the glass-ceramics include which of the following (two best answers): (a) efficiency in processing, (b) electrical conductor, (c) high thermal expansion, and (d) strong, relative to other glasses?

Answers

Answer 1

The properties and characteristics of glass-ceramics include efficiency in processing and being strong, relative to other glasses.

Glass-ceramics are a type of material that combines the properties of both glass and ceramics. They are produced by controlled crystallization of certain glasses, resulting in a material with unique properties. One of the advantages of glass-ceramics is their efficiency in processing. They can be formed and shaped more easily compared to traditional ceramics, making them suitable for various applications. Additionally, glass-ceramics exhibit high strength and toughness, relative to other glasses. This strength is attributed to the presence of crystalline phases within the material structure. Other characteristics such as high thermal expansion and electrical conductivity are not typically associated with glass-ceramics.

Question 1 [10 Marks] In materials science, reinforcement is a constituent of a composite material which increases the composite's stiffness and tensile strength. How will you design a reinforcement material that is made of ceramic matrix. Also give the reasons why you chose that specific material.

Answers

Note as far as material science is concerned, that to create a ceramic matrix reinforcement material, I would use a ceramic material with high strength and stiffness such as silicon carbide.

Why is this so?

This is because it has a high melting point.

I would next use chemical vapor deposition or melt spinning to convert the ceramic material into a fibrous shape, resulting in a fibrous ceramic matrix composite.

Because of the intrinsic qualities of the ceramic matrix, the resultant composite would have high stiffness and tensile strength, making it perfect for applications requiring great strength and endurance, such as aerospace or automotive components.

Answer:

\(P'=0.377hp\)

Explanation:

From the question we are told that:

Initial Temperature T_1=70 F

Final Temperature \(T_2=250pisa =114.94F\)

Efficiency \(E=75\%=0.75\)

Generally the equation for Work-done  is mathematically given by

 \(W=\int C_pT\)

 \(W=10.03(114.94-70 )+0.0184((114.94)^2-70^2 )\)

 \(W=527.21btu/ibmole\)

 \(W=11.982btu/ibm\)

Generally the equation for Efficiency  is mathematically given by

 \(E=\frac{isotropic Power}{Actual P'}\)

 \(E=\frac{P}{P'}\)

Since

Isotropic Power

  \(P=0.0167*11.982btu/ibm\)

 \(P=0.2btu/s\)

Therefore

 \(P'=\frac{0.2}{0.75}\)

 \(P'=0266btu/s\)

If two current are in the same direction at any instant of time in a given branch of a circuit, the net current at that instant

Answers

If two currents are in the same direction at any instant of time in a given branch of a circuit, the net current at that instant will be the sum of the two individual currents. In other words, the net current is the algebraic sum of the two currents.

How can this be illustrated?

For example, if one current is 2 amperes and the other current is 3 amperes, and they are flowing in the same direction in a given branch of the circuit, then the net current at that instant will be 5 amperes (2 + 3 = 5).

It's important to note that this only applies at a specific instant in time, and the net current may change as the circuit changes or the currents vary.

From the top of a vertical cliff 80m high, the angles of depression of 2 buoys lying due west of the cliff are 23° and 15° respectively. How far are the buoys apart?​

Answers

Answer:

  110 m

Explanation:

The geometry of the problem can be modeled by a right triangle. The height of the cliff forms one leg, and the distance to a buoy forms the other leg. The angle of depression is opposite the height of the cliff. An appropriate trig relation is ...

  Tan = Opposite/Adjacent

Solving for the Adjacent side (the distance to the buoy), we find ...

  Adjacent = Opposite/Tan

  distance to buoy 1 = (80 m)/tan(23°) ≈ 188.468 m

  distance to buoy 2 = (80 m)/tan(15°) ≈ 298.564 m

Then the distance between the buoys is ...

  298.564 -188.468 m ≈ 110 m

The buoys are about 110 meters apart.

A closed vessel of volume 80 litres contains 0.5 N of gas at a pressure of 150 kN/m2. If the gas is compressed isothermally to half its volume, determine the resulting pressure.

Answers

Answer:

The resulting pressure of the gas when its volume decreases is 300 kN/m².

Explanation:

Given;

initial volume of the gas, V₁ = 80 L

number of moles of the gas, n = 0.5 moles

initial pressure of the gas, P₁ = 150 kN/m² = 150 kPa

Determine the constant temperature of the gas using ideal gas equation;

PV = nRT

where;

R is ideal gas constant = 8.315 L.kPa/K.mol

T is the constant temperature

\(T = \frac{P_1V_1}{nR} \\\\T = \frac{150.kPa \ \times \ 80 .L}{0.5 .mol \ \times \ 8.315(L.kPa/mol.K)} \\\\T = 2,886.35 \ K\)

When the gas is compressed to half of its volume;

new volume of the gas, V₂ = ¹/₂ V₁

                                             = ¹/₂ x 80L = 40 L

The new pressure, P₂ is calculated as;

\(P_2V_2 = nRT\\\\P_2 = \frac{nRT}{V_2} \\\\P_2 = \frac{0.5 \times 8.315\times 2886.35}{40} \\\\P_2 = 300 \ kPa = 300 \ kN/m^2\)

Therefore, the resulting pressure of the gas when its volume decreases is 300 kN/m².

Technician A says that a wye-wound stator produces more maximum output than the same alternator equipped with a delta-wound stator. Technician B says that an alternator equipped with a delta-wound stator produces more maximum output than a wye-wound stator. Who is right

Answers

The both technicians are correct, but they are referring to different types of maximum output. It's important to understand the differences between these two types of stators and their applications to choose the right one for a specific application.

A wye-wound stator produces more maximum output in terms of maximum line-to-neutral voltage. This is because each phase of the stator winding is connected to a neutral wire, which allows for a higher voltage output compared to a delta-wound stator.

The wye-wound stator is commonly used for applications that require high-voltage output, such as industrial and commercial applications.

On the other hand, an alternator equipped with a delta-wound stator produces more maximum output in terms of maximum current. This is because the delta-wound stator has a lower winding resistance, which allows for a higher current output compared to a wye-wound stator.

The delta-wound stator is commonly used for applications that require high-current output, such as power generation and distribution.

Two character strings may have many common substrings. Substrings are required to be con tiguous in the original string. For example, photograph and tomography have several common substrings of length one (i.e, single letters), and common substrings ph, to, and ograph (as well as all the substrings of ograph). The maximum common substring (MCS) length is 6 Let X = x1x2 . . .2'm and Y-MW2 . . "In be two character strings. (a) Give a dynamic programming algorithm to find the MCS length for X and Y. writhm to find the MCS leugth for X and (b) ofalandthe worst-case running time and space requirements of your algerit in as functions c)Demonstrate your dynamic programming algorithm for finding the MCS length of character strings algorithm and logarithm. by constructing the corresponding dynamic programming tables

Answers

(a) Dynamic Programming Algorithm to find the MCS length for X and Y:

The common substring refers to a string that occurs in two or more strings. The Longest Common Substring (LCS) is a problem that involves finding the longest substring that appears in two or more strings. In this case, the substrings are required to be contiguous in the original string.

To find the Maximum Common Substring (MCS) length for the given string X and Y, we need to use the following dynamic programming algorithm:

Initialize a 2-D array (Table) with all values 0.

For i = 1 to n, where n is the length of string X:

For j = 1 to m, where m is the length of string Y:

if X[i] == Y[j]:

Table[i][j] = Table[i-1][j-1] + 1

if Table[i][j] > length:

length = Table[i][j]

Here, the Table[i][j] represents the length of the longest common suffix of X[1..i] and Y[1..j]. If X[i] and Y[j] are not the same, Table[i][j] is set to 0. The length variable stores the maximum length of all the entries in the Table. The length of the longest common substring is stored in the variable length.

(b) Time and Space Complexity:

The dynamic programming algorithm for the longest common substring takes O(nm) time and O(nm) space in the worst-case scenario. Here, n and m are the lengths of the two input strings X and Y, respectively. Hence, the time and space complexity of the algorithm is O(nm).

(c) Dynamic Programming Tables:

The dynamic programming tables for the strings X = ABCDEFG and Y = ABCEDEFG
