The electric field of a plane wave propagating in a nonmagnetic medium is given by E = 225e-30x cos (2π x 10°t - 40x) [V/m] Obtain the corresponding expression for the magnetic field.
Answers
To obtain the corresponding expression for the magnetic field in a plane wave propagating in a nonmagnetic medium, we can use Maxwell's equations. Specifically, Faraday's law of electromagnetic induction relates the electric field (E) to the magnetic field (B) as follows:
∇ × E = -∂B/∂t
Given the electric field expression E = 225e^(-30x) cos(2π × 10^8 t - 40x) [V/m], we can apply Faraday's law to find the corresponding magnetic field expression.
Taking the curl of both sides of the equation, we have:
∇ × (∇ × E) = ∇ × (-∂B/∂t)
Using vector calculus identities, we can simplify the left side of the equation:
∇ × (∇ × E) = ∇(∇ ⋅ E) - ∇²E
Since the electric field does not have any dependence on y or z, the derivatives with respect to y and z are zero. Therefore, the expression simplifies further:
∇ × (∇ × E) = (0, ∂(∂E/∂x)/∂z - ∂²E/∂x², 0)
Now, equating this to -∂B/∂t, we have:
(0, ∂(∂E/∂x)/∂z - ∂²E/∂x², 0) = -∂B/∂t
To find the expression for the magnetic field (B), we need to solve this equation. However, this involves differentiating the given electric field expression twice with respect to x, which can be quite involved.
The resulting expression for the magnetic field will depend on the specific values and derivatives involved in the electric field expression. To obtain the complete expression for the magnetic field, we would need to carry out the necessary differentiations and simplifications.
The corresponding expression for the magnetic field in a plane wave propagating in a nonmagnetic medium can be obtained by applying Faraday's law of electromagnetic induction. However, in this case, the given electric field expression is quite complex and involves derivatives, making it difficult to provide a direct answer without performing the necessary calculations.

A thin-walled pressure vessel is constructed by rolling a 6 mm thick steel sheet into a cylindrical shape, welding the seam along line A-B, and capping the ends. The vessel is subjected to an internal pressure of 1.25 MPa. What is the normal stress normal to line A-B?
Answers
Answer:
41.015
Explanation:
Solution
Given that:
Th first step to take is to find the longitudinal stress in the cylinder
σl = PD/4t
P = the pressure
D = the diameter
t = the thickness
Thus,
σl = 1.25 * ^ 6 * 0.45 / 4 * 6 * 10 ^ ⁻3
=23.475Mpa
Now. we find the hoop stress in the cylinder∠
σh = PD/2t
σh = 1.25 * ^ 6 * 0.45/ 2 * 6 * 10 ^ ⁻3
σh =46.875 Mpa
Then
we find the normal stress in the line of the 30° angle with the longitudinal axis stated below:
σab = σh + σl/2 + ( σh - σl/2) cos 2θ + t sin 2θ
So,
σab =46.875 + 23.4375/2 + ( 46.875 - 23.4375/2) cos 2(30°) + 0
σab= 41.015
Therefore the normal stress to line A-B is 41.015

Required:
a. Estimate the fatigue factor of safety based on yielding criteria.
b. Estimate the fatigue factor of safety based on Goodman and Morrow criteria.
Answers
Answer:
A) ( N ) = 1.54
B) N ( Goodman ) = 1.133, N ( Morrow) = 1.35
Explanation:
width of steel bar = 25-mm
thickness of steel bar = 10-mm
diameter = 6-mm
load on plate = between 12 kN AND 28 kN
notch sensitivity = 0.83
A ) Fatigue factor of safety based on yielding criteria
= δa + δm = \(\frac{Syt}{n}\) = 91.03 + 227.58 = 490 / N
therefore Fatigue number of safety ( N ) = 1.54
δa (amplitude stress ) = kf ( Fa/A) = 2.162 * ( 8*10^3 / 190 ) = 91.03 MPa
A = area of steel bar = 190 mm^2 , Fa = amplitude load = 8 KN , kf = 2.162
δm (mean stress ) = kf ( Fm/A ) = (2.162 * 20*10^3 )/ 190 = 227.58 MPa
Fm = mean load = 20 *10^3
B) Fatigue factor of safety based on Goodman and Morrow criteria
δa / Se + δm / Sut = 1 / N
= 91.03 / 183.15 + 227.58 / 590 = 1 /N
Hence N = 1.133 ( based on Goodman criteria )
note : Se = endurance limit (calculated) = 183.15 , Sut = 590
applying Morrow criteria
N = 1 / ( δa/Se) + (δm/ δf )
= 1 / ( 91.03 / 183.15 ) + (227.58 / 935 )
= 1.35

A composite wall has a 6-cm layer of fiberglass insulation [K =
0.038 W/(m-°C)] sandwiched between two 2 cm thick white pine boards
[K = 0.10 W/(m-°C)]. Calculate the heat flux per unit area through
Answers
Answer:
Explanation:To calculate the heat flux per unit area through the composite wall, we can use the concept of thermal resistance and Fourier's law of heat conduction. The formula for calculating the heat flux (q) is:
q = (T1 - T2) / R_total
Where:
T1 is the temperature on one side of the wall
T2 is the temperature on the other side of the wall
R_total is the total thermal resistance of the composite wall
The thermal resistance of each layer can be calculated using the formula:
R = thickness / thermal conductivity
Let's calculate the heat flux per unit area step by step:
Calculate the thermal resistance of each layer:
R_fiberglass = 0.06 m / 0.038 W/(m-°C) = 1.58 (m²·°C)/W
R_pine = 0.02 m / 0.10 W/(m-°C) = 0.20 (m²·°C)/W
Calculate the total thermal resistance of the composite wall:
R_total = R_fiberglass + R_pine + R_fiberglass = 1.58 (m²·°C)/W + 0.20 (m²·°C)/W + 1.58 (m²·°C)/W = 3.36 (m²·°C)/W
Determine the temperature difference between the two sides of the wall.
Assume T1 = 100 °C and T2 = 20 °C.
(T1 - T2) = 100 °C - 20 °C = 80 °C
Calculate the heat flux per unit area:
q = (T1 - T2) / R_total = 80 °C / 3.36 (m²·°C)/W ≈ 23.81 (W/m²)
Therefore, the heat flux per unit area through the composite wall is approximately 23.81 W/m².

Process capability, Cp, is a measure of how well a process can meet the specifications. It is calculated by dividing the difference between the upper and lower specification limits by six times the standard deviation of the process. In this case, the upper specification limit is 27, and the lower specification limit is 10. However, the process mean or target value is not provided, which is necessary to calculate Cp accurately. Without the process mean, we cannot determine the process capability.
Regarding the expected dropout per 1,000 opportunities on the upper end, it is calculated based on the shift in the process mean. Since the process was originally centered and the mean shifts up towards the upper specification limit by 0.81 standard deviations, it implies that the process mean moves closer to the upper limit. This shift indicates an increased likelihood of values exceeding the upper limit. To calculate the expected dropout per 1,000 opportunities on the upper end, we need to consider the process capability index, Cpk, which takes into account the mean shift. However, since the necessary information to calculate Cpk (such as the mean, standard deviation, and process specifications) is not provided, we cannot determine the expected dropout accurately.

Air flows through a pipe at a rate of 200 L/s. The pipe consists of two sections of diameters 20 cm and 10 cm with a smooth reducing section that connects them. The pressure difference between the two pipe sections is measured by a water manometer. Neglecting frictional effects, if the inlet temperature of air is at 25oC, due to the compression of the air at neck of the pipe contraction, the outlet temperature is measured at 30oC, determine the differential height of water between the two pipe sections. Take the air density at 25oC and 35oC as 1.20 kg/m3 and 1.19 kg/m3 respectively.
Answers
The differential height between the two pipe sections is 0.05m
What is Differential HeightThe differential height of water between the two pipe sections can be calculated using the following equation:
h = (Q²*(ρ₂-ρ₁)/(A*g)) * (P₂-P₁)
where
h = differential height of water (m)
Q = volumetric flow rate (L/s)
ρ = density of air (kg/m3)
A = cross sectional area of pipe (m2)
g = gravitational acceleration (9.81 m/s2)
P = pressure (Pa)
Substituting the given values in the equation we get,
h = (200*(1.19-1.20)/(π*(0.1)2*9.81)) * (30-25)
h = 0.05 m
