Ball bearing leaving the oven at a uniform temperature a of 900°C are exposed to air for a while before they are dropped into the water for quenching. The time they can stand in the air before their temperature fails to 850°C is to be determined. Properties (k = 15.1W/m. °C, p = 8085 kg/m3, Cp = 0.480 kJ/kg · K)
Answers
To determine the time the ball bearing can stand in the air before its temperature falls to 850°C, we can use the concept of thermal conduction and the equation for heat transfer.
The equation for heat transfer through conduction is given by:
Q = (k * A * (T2 - T1)) / d
where:
Q is the heat transfer rate,
k is the thermal conductivity of the material,
A is the surface area of the ball bearing,
T1 is the initial temperature of the ball bearing,
T2 is the final temperature of the ball bearing,
and d is the thickness of the air layer surrounding the ball bearing.
We can rearrange the equation to solve for time:
t = (m * Cp * (T1 - T2)) / Q
where:
t is the time,
m is the mass of the ball bearing,
Cp is the specific heat capacity of the ball bearing,
T1 is the initial temperature of the ball bearing,
T2 is the final temperature of the ball bearing,
and Q is the heat transfer rate.
To calculate the heat transfer rate, we need to determine the surface area of the ball bearing, which depends on its shape. Additionally, we need to know the mass of the ball bearing.
Once we have these values, we can substitute them into the equation to find the time the ball bearing can stand in the air before its temperature falls to 850°C.

A germanium diode carries a current of 1 mA at room temperature when a forward bias of 0.15v is applied. Estimate the reverse saturation current at room temperature.
Answers
I = I0 * (exp(qV/kT) - 1)
where I is the current through the diode, q is the charge of an electron, V is the voltage across the diode, k is Boltzmann's constant, and T is the temperature in Kelvin.
At room temperature, T = 298 K. We are given that the diode carries a current of 1 mA when a forward bias of 0.15 V is applied. Let's assume that the diode is ideal, meaning that it has no series resistance, so the voltage across the diode equals the forward bias voltage.
Plugging in these values, we get:
1E-3 A = I0 * (exp((1.602E-19 C)(0.15 V) / (1.381E-23 J/K)(298 K)) - 1)
Simplifying, we get:
1E-3 A = I0 * (exp(0.01275) - 1)
1E-3 A / (exp(0.01275) - 1) = I0
I0 = 2.34E-12 A, or approximately 0.23 nA. Therefore, the estimated reverse saturation current at room temperature is 0.23 nA.

Answers
The rate of heat transfer through the wall is approximately 130 W.
No, we cannot ignore the steel bars between the plates in the heat transfer analysis because they contribute to the overall thermal resistance of the wall.
While they may only occupy a small percentage of the heat transfer surface area, they still have an impact on the rate of heat transfer through the wall.
By including the thermal resistance of the steel bars in the analysis, we can obtain a more accurate estimate of the heat transfer rate.
To calculate the heat transfer rate, we can use the formula Q = (kAΔT)/d, where Q is the heat transfer rate, k is the thermal conductivity, A is the area of heat transfer, ΔT is the temperature difference, and d is the thickness of the wall.
By applying this formula to the given data, we can calculate that the rate of heat transfer through the wall is approximately 130 W.

how does resurfacing the cylinder head of an OHC engine affect valve timing and what should be done when the head needs resurfacing ?
Answers
Resurfacing the cylinder head of an OHC (Overhead Cam) engine can affect valve timing by altering the distance between the camshaft and the valves. If the head is resurfaced too much, the valve timing can be advanced, meaning that the valves will open and close earlier than they should, leading to poor engine performance.
When the head needs resurfacing, it is important to consult the manufacturer's specifications to determine the maximum amount that can be removed from the head without affecting the valve timing. In some cases, it may be necessary to replace the camshaft and adjust the valve clearances after resurfacing the head to ensure that the valve timing is correct.
Additionally, it is important to inspect the valve seats and replace them if they are worn or damaged. This is because resurfacing the head can affect the valve seats and lead to valve leakage, which can cause engine performance issues. By inspecting and replacing the valve seats as needed, the engine can maintain proper compression and operate at peak performance.

A cylindrical bar of metal having a diameter of 20.5 mm and a length of 201 mm is deformed elastically in tension with a force of 46300 N. Given that the elastic modulus and Poisson's ratio of the metal are 60.5 GPa and 0.33, respectively, determine the following: (a) The amount by which this specimen will elongate in the direction of the applied stress. (b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.
Answers
Answer:
a) The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm
b) The change in diameter of the specimen is - 0.015 mm
Explanation:
Given the data in the question;
(a) The amount by which this specimen will elongate in the direction of the applied stress.
First we find the area of the cross section of the specimen
A = \(\frac{\pi }{4}\) d²
our given diameter is 20.5 mm so we substitute
A = \(\frac{\pi }{4}\) ( 20.5 mm )²
A = 330.06 mm²
Next, we find the change in length of the specimen using young's modulus formula
E = σ/∈
E = P/A × L/ΔL
ΔL = PL/AE
P is force ( 46300 N), L is length ( 201 mm ), A is area ( 330.06 mm² ) and E is elastic modulus (60.5 GPa) = 60.5 × 10⁹ N/m² = 60500 N/mm²
so we substitute
ΔL = (46300 N × 201 mm) / ( 330.06 mm² × 60500 N/mm² )
ΔL = 0.466 mm
Therefore, The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm
(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.
Using the following relation for Poisson ratio
μ = - Δd/d / ΔL/L
given that Poisson's ratio of the metal is 0.33
so we substitute
0.33 = - Δd/20.5 / 0.466/201
0.33 = - Δd201 / 20.5 × 0.466
0.33 = - Δd201 / 9.143
0.33 × 9.143 = - Δd201
3.01719 = -Δd201
Δd = 3.01719 / - 201
Δd = - 0.015 mm
Therefore, The change in diameter of the specimen is - 0.015 mm

Answers
Answer:
NG=64 teeth
dG=384mm
dP=96mm
C=240mm
Explanation:
step one:
given data
module m=6mm
velocity ratio VR=4
number of teeth of pinion Np=16
Step two:
Required
1. Number of teeth on the driven gear
\(N_G=N_P*V_R\\\\N_G=16*4\\\\N_G=64\)
The driven gear has 64 teeth
2. The pitch diameters
The driven gear diameter
\(d_G=N_G*m\\\\d_G=64*6\\\\d_G=384\)
The driven gear diameter is 384mm
The pinion diameter
\(d_P=N_P*m\\\\d_P=16*6\\\\d_P=96\)
Pinion diameter is 96mm
3. Theoretical center-to-center distance
\(C=\frac{d_G+d_P}{2} \\\\C=\frac{384+96}{2} \\\\C=\frac{480}{2}\\\\C=240\)
The theoretical center-to-center distance is 240mm
The results are listed below:
The driven gear has 64 teeth.The pinion has a diameter of 96 millimeters and the driven gear has a diameter of 384 millimeters.The theoretical center-to-center distance is 240 millimeters.First, we proceed to find the number of teeth of each gear (\(N_{D}, N_{P}\)) based on the fact that gear only fit when they have the same module (\(m\)). The velocity ratio (\(r_{v}\)) is defined by the following relationship:
\(r_{v} = \frac{N_{D}}{N_{P}}\) (1)
If we know that \(r_{v} = 4\) and \(N_{P} = 16\), then the number of teeth of the driven gear is:
\(N_{D} = r_{v}\cdot N_{P}\)
\(N_{D} = 4\cdot (16)\)
\(N_{D} = 64\)
The driven gear has 64 teeth.
The pitch diameter (\(D\)) is obtained by multiplying the number of teeth (\(N\)) by module (\(m\)), in milimeters.
Pinion
\(D_{P} = m\cdot N_{P}\) (2)
(\(m = 6\,mm\), \(N_{P} = 16\))
\(D_{P} = (6\,mm)\cdot (16)\)
\(D_{P} = 96\,mm\)
Driven gear
\(D_{D} = m\cdot N_{D}\) (3)
(\(m = 6\,mm\), \(N_{D} = 64\))
\(D_{D} = (6\,mm)\cdot (64)\)
\(D_{D} = 384\,mm\)
The pinion has a diameter of 96 millimeters and the driven gear has a diameter of 384 millimeters.
Lastly, the theoretical center-to-center distance is calculated by the following formula:
\(d = \frac{1}{2}\cdot (D_{P}+D_{D})\) (4)
(\(D_{P} = 96\,mm\), \(D_{D} = 384\,mm\))
\(d = \frac{1}{2}\cdot (96\,mm + 384\,mm)\)
