Answers
A, B, and C act as the select lines for the 8-to-1 Multiplexer. The inputs to the Multiplexer are connected to A, B, C, D, E, F, G, and H, while the output of the Multiplexer is F.
Question 1: Design a logic circuit that has three inputs, A, B, and C, and whose output will be HIGH only when a majority of the inputs are LOW.
The logic circuit can be designed using a combination of AND and NOT gates. To achieve an output HIGH when a majority of the inputs are LOW, we need to check if at least two of the inputs are LOW. We can implement this as follows:
Connect the three inputs (A, B, and C) to separate NOT gates, producing their complements (A', B', and C').
Connect the three original inputs (A, B, and C) and their complements (A', B', and C') to AND gates.
Connect the outputs of the AND gates to a majority gate, which is an OR gate in this case.
The output of the majority gate will be the desired output of the circuit.
Truth Table:
A B C Output
0 0 0 0
0 0 1 0
0 1 0 0
0 1 1 1
1 0 0 0
1 0 1 1
1 1 0 1
1 1 1 1
In the truth table, the output is HIGH (1) only when a majority of the inputs (two or three) are LOW (0).
To implement this circuit using only NAND gates, we can replace each AND gate with a NAND gate followed by a NAND gate acting as an inverter.
Question 2: Implement the Boolean expression F = AB + BC + ACD using a 4-to-1 Multiplexer with A and B as selectors. Sketch the final circuit.
To implement the given Boolean expression using a 4-to-1 Multiplexer, we can assign the inputs A, B, C, and D to the select lines of the Multiplexer. The output of the Multiplexer will be the desired F.

In a compression test, a steel test specimen (modulus of elasticity 30 106 lb/in2 ) has a starting height 2.0 in and diameter 1.5 in. The metal yields (0.2% offset) at a load 140,000 lb. At a load of 260,000 lb, the height has been reduced to 1.6 in. Determine (a) yield strength and (b) fl ow curve parameters (strength coeffi cient and strain-hardening exponent). Assume that the cross-sectional area increases uniformly during the test.
Answers
Answer:
A) σ_y = 79096 lb/in² = 79.1 ksi
B) strain-hardening exponent = 0.102
(strength coefficient = 137838.78 lb/in²
Explanation:
A) Formula for volume is;
V = πd²h/4
We are given;
height 2.0 in and diameter 1.5 in
Thus;
V = (π × 1.5² × 2)/4
V = 3.53 in³
Area is;
A = πd²/4
A = (π × 1.5²)/4
A = 1.77 in²
Yield strength is gotten from the formula;
σ_y = Force/Area
We are given load = 140,000 lb
Thus;
σ_y = 140000/1.77
σ_y = 79096 lb/in²
B) We are given
modulus of elasticity: E = 30 × 10^(6) lb/in²
Formula for strain is;
ε = σ_y/E
ε = 79096/(30 × 10^(6))
ε = 0.00264
The metal yields (0.2% offset), thus;
strain offsets = 0.00264 + 0.002
strain offsets: ε1 = 0.00464
Thus;
(h_i - h_o)/h_o = 0.00464
(h_i/h_o) - 1 = 0.00464
(h_i/h_o) = 1.00464
h_i = h_o(1.00464)
h_o = 2 in
Thus; h_i = 2(1.00464) = 2.00928 in
Area = Volume/height = 3.53/2.00928 = 1.757 in²
True stress is;
σ = force/area = 140000/1.757
σ1 = 79681.27 lb/in²
At a load of 260,000 lb, the height has been reduced to 1.6 in. Thus;
Area = 3.53/1.6 = 2.206 in²
True stress is;
σ2 = 260000/2.206
σ2 = 117860.38 lb/in²
True strain;
ε2 = In(2/1.6)
ε2 = 0.223
From flow curve;
σ = kεⁿ
Thus;
σ1 = k(ε1)ⁿ
79681.27 = k(0.00464ⁿ) - - - (eq 1)
Also for σ2 = k(ε2)ⁿ;
117860.38 = k(0.223ⁿ) - - - - - (eq 2)
From eq 1,
k = 79681.27/0.00464ⁿ
Putting this for k in eq2 to get;
117860.38 = (0.223ⁿ) × 79681.27/0.00464ⁿ
117860.38/79681.27 = 0.223ⁿ/0.00464ⁿ
Solving for n, we have ≈ 0.102
Thus,K is;
k = 79681.27/0.00464^(0.102)
k = 137838.78 lb/in²

Refrigerants from a refrigeration system that has a burned out motor-compressor assembly can be dangerous because it could contain a high concentration of ____________________. Question 25 options:
Answers
Refrigerants from a refrigeration system that has a burned out motor-compressor assembly can be dangerous because it could contain a high concentration of toxic chemicals such as chlorine, fluorine, or bromine. These chemicals can pose a significant danger to the environment and human health, especially if they are released into the atmosphere.
In a refrigeration system, the refrigerant is responsible for absorbing heat from the inside of the unit and releasing it outside. This process is repeated continuously to maintain the desired temperature. The compressor is the heart of the refrigeration system, and it compresses the refrigerant gas to increase its temperature and pressure so that it can release the heat it has absorbed. If the motor-compressor assembly burns out, the refrigerant may not be circulated properly, which can cause it to stagnate and decompose.
These chemicals can be harmful to people and the environment if they are released into the atmosphere.To avoid these hazards, it is essential to handle refrigerants carefully, especially when repairing or disposing of refrigeration units. Technicians who handle refrigerants must be trained and certified to ensure that they know how to handle these chemicals safely. They must follow proper procedures for handling and disposing of refrigerants to prevent environmental contamination and protect human health.
In summary, the refrigerants from a refrigeration system that has a burned out motor-compressor assembly can be dangerous because it could contain a high concentration of toxic chemicals such as chlorine, fluorine, or bromine, and it is important to handle these chemicals carefully to avoid environmental contamination and protect human health.

Steam enters an adiabatic turbine at 800 psia and9008F and leaves at a pressure of 40 psia. Determine themaximum amount of work that can be delivered by thisturbine.
Answers
Answer:
\(w_{out}=319.1\frac{BTU}{lbm}\)
Explanation:
Hello,
In this case, for the inlet stream, from the steam table, the specific enthalpy and entropy are:
\(h_1=1456.0\frac{BTU}{lbm} \ \ \ s_1=1.6413\frac{BTU}{lbm*R}\)
Next, for the liquid-vapor mixture at the outlet stream we need to compute its quality by taking into account that since the turbine is adiabatic, the entropy remains the same:
\(s_2=s_1\)
Thus, the liquid and liquid-vapor entropies are included to compute the quality:
\(x_2=\frac{s_2-s_f}{s_{fg}}=\frac{1.6313-0.39213}{1.28448}=0.965\)
Next, we compute the outlet enthalpy by considering the liquid and liquid-vapor enthalpies:
\(h_2=h_f+x_2h_f_g=236.14+0.965*933.69=1136.9\frac{BTU}{lbm}\)
Then, by using the first law of thermodynamics, the maximum specific work is computed via:
\(h_1=w_{out}+h_2\\\\w_{out}=h_1-h_2=1456.0\frac{BTU}{lbm}-1136.9\frac{BTU}{lbm}\\\\w_{out}=319.1\frac{BTU}{lbm}\)

In a dispute between Cosmic Games Corporation and Mythic Engineering Associates, Inc., the court applies the doctrine of stare decisis. What is this doctrine? What does this doctrine have to do with the American legal system?
Answers
The doctrine of stare decisis is a legal principle that involves adhering to previous court decisions when deciding similar cases.
It is a fundamental aspect of the American legal system, promoting consistency, stability, and predictability in the interpretation and application of laws.
The doctrine of stare decisis, which means "to stand by things decided," is a concept in the legal system that requires courts to follow and adhere to previous decisions or precedents when deciding cases with similar facts or legal issues. It promotes stability and consistency in the interpretation and application of laws by ensuring that similar cases are treated similarly.
Under this doctrine, once a court has established a legal principle or precedent, it is generally binding on lower courts within the same jurisdiction. This means that judges are obligated to follow the reasoning and outcome of previous cases when faced with similar legal issues. However, stare decisis also allows for the possibility of overruling or departing from precedent in exceptional circumstances or when there is a compelling reason to do so.
In the American legal system, the doctrine of stare decisis plays a crucial role in providing predictability and stability in the law. It ensures that similar cases are treated consistently, and the decisions made by higher courts serve as guiding principles for lower courts. Stare decisis contributes to the development of legal principles, the preservation of legal precedents, and the overall integrity and fairness of the legal system.

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
