Describe how you would use principles of series circuit to analyze a parallel circuit. What formulas used in a series circuit analysis would not apply?
Answer:
The principles of a series circuit that can be used to analyze a parallel circuit is that of calculating total resistance in the circuits.
The formula used in a series circuit analysis for finding total resistance is different from that used in a parallel circuit for finding overall resistance. i.e.
For a series circuit total resistance Rt={R1+R2+R3+.......Rn}
For a parallel circuit, total resistance 1/Rt ={1/R1+1/R2+1/R3+.....1/Rn]
Explanation:
In a series circuit, the current passing through each component is the same where as in a parallel circuit the voltage through each component is the same.
The principles of series circuit that can be used to analyze a parallel circuit is that of calculating total resistance in the circuits. In a series circuit, total resistance is calculated as the sum of resistance of the components connected to the circuit, where as in a parallel circuit, overall resistance is the summation of the resistance of individual components.
This means you can use principles of series circuit to find total resistance then use that value to confirm the individual resistance values of components in a parallel circuits. This is possible because you will have the expected total resistance [calculated from the series circuit], then the sum of resistance of the same but individual components now in the parallel circuit should be equal to the total resistance calculated from the series circuit.
The formula for calculating resistance in series circuit given as :{Rt= R1+R2+R3+.......Rn} where Rt is the total resistance and R1,R2,R3...Rn are the values of individual components in the series circuit, can not be used in finding overall resistance in a parallel circuits because the formula for total resistance will change to : [1/Rt =1/R1+1/R2+1/R3+.....1/Rn]

Obtain the solution when the initial liquid temperature is 100 c, the ambient temperature is 2 and the thermal time constant is 60 min. 3. Plot the solution. Remember to label the axis. 4. Calculate the fluid temperature after one time constant.
The Stefan-Boltzmann law can be employed to estimate the rate of radiation of energy H from a surface, as in
H = Aeσ^4
where H is in watts, A = the surface area (m^2 ), e = the emissivity that characterizes the emitting properties of the surface (dimensionless), σ = a universal constant called the Stefan-Boltzmann constant (= 5.67 x 10^8 W m^2 K^-4 ), and T = absolute temperature (K).
Required:
Determine the error of H for a steel plate with A = 0.15 m^2 , e = 0.90, and T 5 650 ± 20.
b. Compare your results with the exact error. Repeat the computation but with T = 650 ± 40. Interpret your results.
Explanation:
A.
H = Aeσ^4
Using the stefan Boltzmann law
When we differentiate
dH/dT = 4AeσT³
dH/dT = 4(0.15)(0.9)(5.67)(10^-8)(650)³
= 8.4085
Exact error = 8.4085x20
= 168.17
H(650) = 0.15(0.9)(5.67)(10^-8)(650)⁴
= 1366.376watts
B.
Verifying values
H(T+ΔT) = 0.15(0.9)(5.67)(10)^-8(670)⁴
= 1542.468
H(T+ΔT) = 0.15(0.9)(5.67)(10^-8)(630)⁴
= 1205.8104
Error = 1542.468-1205.8104/2
= 168.329
ΔT = 40
H(T+ΔT) = 0.15(0.9)(5.67)(10)^-8(690)⁴
= 1735.05
H(T-ΔT) = 0.15(0.9)(5.67)(10^-8)(610)⁴
= 1735.05-1059.83/2
= 675.22/2

A strip footing of width 3 m is founded at a depth of 2 m below the ground surface in a (c – 0) soil having a cohesion c = 30 kN/m2 and angle of shearing resistance 0 = 35°. The water table is at a depth of 5 m below ground level. The moist weight of soil above the water table is 17.25 kN/m3. Determine the find ultimate bearing capacity of the soil.
Using Terzagi's Equation as shown in the attachement;
Qa = 4225 kN/m
As per the given data, the ultimate bearing capacity of the soil is 313 kN/[tex]m^2[/tex]
What is bearing capacity?Bearing capacity is the capacity of soil to support loads applied to the ground in geotechnical engineering.
To determine the ultimate bearing capacity of the soil, we can use the following formula:
q_ult = cN_c + 0.5γ*(BN_q + 0.4N_g*(B - B_f)*N_q)
To find the values of N_c, N_q, and N_g, we can use the following equations:
N_c = [cot(0) + tan(φ)][1 + 0.2(B_f/D)][(N_q/N_c) - 1][(N_q/N_c) - 2]
N_q = [(1 + sin(0))(1 - sin(0))][(N_q/N_c) - 1]
N_g = 0.5*(N_q - 1)*tan^2(φ)
Using the above equations, we can calculate the values of N_c, N_q, and N_g as follows:
N_c = [cot(35°) + tan(35°)][1 + 0.2(3/2)][(2.45/N_c) - 1][(2.45/N_c) - 2] ≈ 11.5
N_q = [(1 + sin(35°))(1 - sin(35°))][(2.45/N_c) - 1] ≈ 10.5
N_g = 0.5*(10.5 - 1)*[tex]tan^2[/tex](35°) ≈ 2.6
Substituting these values into the formula for q_ult, we get:
q_ult = 3011.5 + 0.517.25*(310.5 + 0.42.6*(3 - 3)*10.5) ≈ 313 kN/m^2
Therefore, the ultimate bearing capacity of the soil is approximately 313 kN/m^2.

L = A·R/ρ
The power is the ratio of energy to time:
P = E/t = (8 J)/(0.25 s) = 32 W
The required resistance is ...
R = V²/P = (240 V)²/(32 W) = 1800 Ω
__
Then the required wire length is ...
L = (π/4)(0.00016 in × 2.54 cm/in)²×(1800 Ω)/(2.825×10^-6 Ω·cm)
L ≈ 82.65 cm
The length of aluminum wire required is about 82.7 cm or 32.5 in.

Consider a carbon fiber reinforced epoxy composite. The fibers are continuous, unidirectionally aligned and 40% by volume. The tensile strength of carbon fibers is 2998 MPa, and the Young's modulus is 214 GPa. The tensile strength of the epoxy matrix is 100 MPa, and its Young's modulus is 3 GPa.
Required:
a. Compute the Young's modulus and the tensile strength of the composite in the longitudinal direction.
b. What is Young's modulus in the longitudinal direction?
Answer:
- the Young's modulus of the composite in the longitudinal direction = 87.4GPa.
- The tensile strength of the composite in the longitudinal direction = 1.26 × 10⁹.
Explanation:
The following parameters or data were given in this particular question/problem;
1. "The fibers are continuous, unidirectionally aligned and 40% by volume."
2." The tensile strength of carbon fibers is 2998 MPa, and the Young's modulus is 214 GPa."
3. " The tensile strength of the epoxy matrix is 100 MPa, and its Young's modulus is 3 GPa."
So, let us delve right into the solution to this question:
[ kindly note that part b. of this problem is the same as the part a. of the problem
Also, in point 2. above 2998MPa = 2.998 =GPa, approximately 3GPa].
40% = 40/100 = 0.4. Therefore, 1 - 0.4 = 0.6. Hence, the Young's modulus of the composite in the longitudinal direction = 3 × 0.6 + 214 × 0.4 = 1.8 + 85.6 = 87.4GPa
The tensile strength of the composite in the longitudinal direction = 100 × 10⁶ × 0.6 + 3 × 10⁹ ₓ 0.4 = 1.26 × 10⁹.

This car is parked. The engine is off and there is no music playing, What energy is currently in use?
Answer:
Potential energy
Explanation:
"Potential energy" is a type of energy an object has when it's at rest or in this case not moving. The car is parked, and the engine is off, that means there is no electrical, kinetic, thermal, or mechanical energy in play since the engine isn't running and the car isn't moving. The radio is off too so that means there is no sound energy or electric energy (again) in play either. You are just parked with the car completely shut off, but you do have the potential to move the car by turning on the engine and start driving, which means potential energy is currently in use.

Consider a convergent duct with an inlet area A1 = 5 m2. Air enters this duct with a velocity V1=10m/s and leaves the duct exit with a velocity V2=30 m/s.
Required:
a. What is the area of the duct exit?
b. If the air pressure and temperature at the inlet area are 1.2 x105 N/m2, and 300K, respectively, what is the pressure at the exit?
Answer:
(a) The area of the duct exit is 1.67 m²
(b) The air pressure at the exit is 1.195 x 10⁵ N/m²
Explanation:
Given;
inlet area, A₁ = 5 m²
inlet velocity, V₁ = 10 m/s
exit velocity, V₂ = 30 m/s
(a) The area of the duct exit is determined by applying continuity equation;
A₁V₁ = A₂V₂
Where;
A₂ is the area of the duct exit
A₂ = (A₁V₁) / (V₂)
A₂ = (5 x 10) / (30)
A₂ = 1.67 m²
(b) Apply Bernoulli’s equation to determine the pressure at the exit;
[tex]P_1 + \frac{\rho V_1^2}{2} = P_2 + \frac{\rho V_2^2}{2}\\\\P_2 = P_1 + \frac{\rho V_1^2}{2} - \frac{\rho V_2^2}{2}\\\\P_2 = P_1 + \frac{\rho }{2} (V_1^2 - V_2^2)[/tex]
Density of air at 300k = 1.177 kg/m³
[tex]P_2 = P_1 + \frac{\rho }{2} (V_1^2 - V_2^2)\\\\P_2 = 1.2*10^5 \ + \ \frac{1.177}{2} (10^2 - 30^2)\\\\P_2 = 1.2*10^5 \ + \ -470.8\\\\P_2 = 1.195*10^5 \ N/m^2[/tex]
Therefore, the air pressure at the exit is 1.195 x 10⁵ N/m²
