(a) The solution to the system of equation is, x = (d + b)/(ad - cb) and y = (-a - c)/(ad - cb).
(b) The condition at which the solution exists is, ad - cb ≠ 0.
Solving the system of equation with Cramer's rule
ax + by = 1
cx + dy = -1
D = [a b]
[c d]
D = ad - cb
Dx = [1 b]
[-1 d]
Dx = d + b
Dy = [a 1]
[c - 1]
Dy = -a - c
x = Dx/D
x = (d + b)/(ad - cb)
y = Dy/D

Water is the working fluid in an ideal Rankine cycle. Superheatedvapor enters the turbine at 10MPa, 480°C, and the condenser pressure is6 kPa. Isentropic efficiencies of the turbine and pump are 80% and 75%,respectively. Determine for the cyclea.the actual heat transfer to the working fluid passing through thesteam generator, in kJ per kg of steam flowing.b.the thermal efficiency.c.the actual heat transfer from the working fluid passing through thecondenser to the cooling water, in kJ per kg of steam flowing
Answers
Answer:
Explanation:
Given that:
Superheated vapor enters the turbine at 10 MPa, 480°C,
From the tables of superheated steam tables; the following values are obtained
\(h_1 = 3322.02 \ kJ/kg\\\\ s_1 = 6.52846 \ kJ/kg.K\)
Also; from the system, the isentropic line is 1-2 in which s_2 is in wet state
\(s_2 = s_{f \ 6 kpa} +xs_{fg \ 6 kpa}\)
\(s_2 =0.51624 + x(7.82)\)
\(s_2 =0.51624 + 7.82x\)
From the values obtained;
\(s_1 =s_2= 6.52846 \ kJ/kg.K\)
Therefore;
6.52846 = 0.51624+7.82x
6.52846 - 0.51624 = 7.82 x
6.01222 = 7.82 x
x = 6.01222/7.82
x = 0.7688
The enthalpy for this process at state (s_2) can be determined as follows:
\(h_2 = h _f +xh_{fg} \\ \\ h_2 = 150.15 +(0.77 \times 2415.92) \\ \\ h_2 =150.15 +( 1629.2584 ) \\ \\ h_2 =2010.4084 \ kJ/kg\)
The actual enthalpy at s_2 by using the isentropic efficiency of the turbine can determined by using the expression:
\(n_T = \dfrac{h_1-h_{2a}}{h_1-h_2}\)
\(0.8 = \dfrac{3322.02-h_{2a}}{3322.02-2010.4084}\)
\(0.8 = \dfrac{3322.02-h_{2a}}{1311.6116}\)
\(0.8 * {1311.6116}= {3322.02-h_{2a}\)
\(1049.28928= {3322.02-h_{2a}\)
\(h_{2a}= {3322.02- 1049.28928\)
\(h_{2a}= 2272.73072\) kJ/kg
The work pump is calculated by applying the formula:
\(w_p = v_{f \ 6 kpa} (p_4-p_3)\)
\(w_p = 0.0010062 * (10000-6)\)
\(w_p = 0.0010062 *9994\)
\(w_p = 10.0559628 \ kJ/kg\)
However;
\(w_p = h_4 -h_3\)
From the process;
\(h_3 = h_{f(6 kpa)} = 150.15 \ kJ/kg\)
\(10.0559628 = h_4 - 150.15\)
\(10.0559628+ 150.15 = h_4\)
\(160.2059628= h_4\)
\(h_4= 160.2059628 \ kJ/kg\)
The actual enthalpy at s_4 by using the isentropic efficiency of the turbine can determined by using the expression:
\(n_P = \dfrac{h_4-h_{3}}{h_{4a}-h_3}\)

For a simply supported beam with a non-centered point loading, where would the approximate location of the maximum deflection be?
Answers Options:
at the end of the beam length
between the farther support and the load
at the center of the beam
between the closer support and the load
Answers
The maximum deflection for a simply supported beam with a non-centered point loading would be at the center of the beam. (option C)
What is the explanation for the above?When the point load is also at the mid-span, the absolute maximum deflection occurs. And it equals P l 3 48 E I. As a result, the distance between point 'P' and the right end for maximum deflection is equal to L/2, i.e. a = L/2.
Typically, support beams are built of wood, steel, or concrete. Among the numerous support, beams are: Cantilever - This beam only has an anchor at one end, leaving the other end unattached and swinging free. This beam is fixed because it is attached on both ends and will not rotate or move at the fulcrum.

Answers
A practice sequence in which a significant amount of time is spent on one task before practicing the next task is referred to as "blocked practice."
Blocked practice involves focusing on a single skill or task for an extended period of time, repeatedly performing it until a certain level of proficiency is achieved before moving on to the next task. This approach allows individuals to concentrate their efforts on mastering a specific skill before progressing to the next one.
Blocked practice can be particularly useful when initially learning a new skill or when refining specific aspects of a complex task. It allows for concentrated and focused practice, enabling individuals to develop muscle memory, improve technique, and build confidence in performing a particular task.
However, it's important to note that while blocked practice can lead to short-term improvements and mastery of individual skills, it may not facilitate as much transfer of learning to real-world situations or promote overall skill development as much as other practice methods like random or varied practice. Therefore, a balanced combination of practice sequences, including both blocked and varied practice, is often recommended for comprehensive skill acquisition and retention.

A cylindrical specimen of steel has an original diameter of 12.8 mm. It is tested in tension its engineering fracture strength is found to be 460 MPa. If the cross-sectional diameter at fracture is 10.7 mm, determine (max. pts. 8): a. The ductility in terms of percent reduction in area b. The true stress at fracture
Answers
Answer:
a) The ductility = -30.12%
the negative sign means reduction
Therefore, there is 30.12% reduction
b) the true stress at fracture is 658.26 Mpa
Explanation:
Given that;
Original diameter \(d_{o}\) = 12.8 mm
Final diameter \(d_{f}\) = 10.7
Engineering stress \(\alpha _{E}\) = 460 Mpa
a) determine The ductility in terms of percent reduction in area;
Ai = π/4(\(d_{o}\) )² ; Ag = π/4(\(d_{f}\) )²
% = π/4 [ ( (\(d_{f}\) )² - (\(d_{o}\) )²) / ( π/4 (\(d_{o}\) )²) ]
= ( (\(d_{f}\) )² - (\(d_{o}\) )²) / (\(d_{o}\) )² × 100
we substitute
= [( (10.7)² - (12.8)²) / (12.8)² ] × 100
= [(114.49 - 163.84) / 163.84 ] × 100
= - 0.3012 × 100
= -30.12%
the negative sign means reduction
Therefore, there is 30.12% reduction
b) The true stress at fracture;
True stress \(\alpha _{T}\) = \(\alpha _{E}\) ( 1 + \(E_{E}\) )
\(E_{E}\) is engineering strain
\(E_{E}\) = dL / Lo
= (do² - df²) / df² = (12.8² - 10.7²) / 10.7² = (163.84 - 114.49) / 114.49
= 49.35 / 114.49
\(E_{E}\) = 0.431
so we substitute the value of \(E_{E}\) into our initial equation;
True stress \(\alpha _{T}\) = 460 ( 1 + 0.431)
True stress \(\alpha _{T}\) = 460 (1.431)
True stress \(\alpha _{T}\) = 658.26 Mpa
Therefore, the true stress at fracture is 658.26 Mpa

Draw the combinational circuit that directly implements the Boolean expression: a) F(x,y,z)=(x(y XOR z)) + (xz)' b) F(x,y,z) = x + xy + y'z
Answers
Answer:
a) Here's how you can draw the combinational circuit that directly implements the Boolean expression F(x,y,z) = (x(y XOR z)) + (xz)':
```
+----(AND)----+
| |
x----( )----( )----+----(OR)----F
| | |
| +----(NOT)----( )
| |
y----( )----------------( )----(AND)----F
| |
+----(XOR)----------( )
|
z-----------------------( )
```
This circuit consists of two AND gates, one OR gate, one NOT gate, and one XOR gate. The XOR gate calculates the value of y XOR z. The first AND gate multiplies x by the output of the XOR gate. The second AND gate multiplies x' by z. The NOT gate inverts the output of the second AND gate, and the OR gate sums the outputs of the first AND gate and the NOT gate to produce the final output F.
b) Here's how you can draw the combinational circuit that directly implements the Boolean expression F(x,y,z) = x + xy + y'z:
```
+----(OR)----+

For part a) of your question, the Boolean expression F(x,y,z) = (x(y XOR z)) + (xz)' can be implemented using the following combinational circuit:
```
+-------+ +-----+ +-----+
x ---| |----| XOR |---| AND |--- F(x,y,z)
| | +-----+ | |
y ---| | | |
| AND |-------------| |
z ---| | | NOT |
| |-------------| |
+-------+ +-----+
```
As you can see, the circuit has two main components: an XOR gate and an AND gate. The XOR gate takes the inputs y and z and outputs their exclusive OR, which is then ANDed with x to produce one term of the final expression. The second term is generated by taking the complement of xz using a NOT gate, and then ANDing it with y.
For part b) of your question, the Boolean expression F(x,y,z) = x + xy + y'z can be implemented using the following combinational circuit:
```
+-------+ +-----+ +-------+
x ---| |---| |---| |
| | | AND | | |--- F(x,y,z)
y ---| OR |---| |---| AND |
| | +-----+ | |
z ---| NOT | | |
| |-------------| |
+-------+ +-------+
```
In this circuit, the inputs x, y, and z are combined in two separate stages. The first stage consists of an AND gate that takes x and y as inputs, and outputs their product xy. The second stage uses two AND gates and an OR gate to combine xy and y'z into the final output. The first AND gate takes xy and z as inputs, and outputs their product xyz. The second AND gate takes y' and z as inputs, and outputs their product y'z. Finally, the OR gate combines the two products xyz and y'z into the final output F(x,y,z).

The 15-Mg tank car A and 25-Mg freight car B travel towards each other with the velocities shown. If the coefficient of restitution between the bumpers is e = 0.8, determine the speed of each car just after the collision. Part A. Determine the speed of the car A just after the collision. Part B. Determine the speed of the car B just after the collision.
Answers
The speed of the car A is 6.05 m/s and the speed of the car B just after the collision 7.65 m/s.
Ma=15 mg , Mb=25mg
Vai=5 m/s vbi=7 m/s
We know coeffecient of restitution
e=|Vaf-Vbf/Vai-Cbi|
0.8=|Vaf-Vbf/5-7|
Vaf-Vbf=1.6
MaVa+mbVb=MaVaf+MbVbf
15*5*25*7=15Vaf+25Vbf
3Vaf+5Vbf=50
sovleving eq 1 and 2
Vbf =6.05 m/s
Vaf=7.65 m/s
The speed of a change in an object's location in any direction. The distance traveled divided by the time required to travel that distance is the definition of speed.Due to its lack of magnitude and merely having a direction, speed is a scalar number. The average speed of an object can be determined if you know the distance traveled and the time it took. Distance times speed is how speed is calculated.
