the critical resolved shear stress for copper (cu) is 0.48 mpa (70 psi). determine the maximum possible yield strength for a single crystal of cu pulled in tension.

Answers

Answer 1

The maximum possible yield strength for a single crystal of copper (Cu) pulled in tension can be determined using the critical resolved shear stress.

How can the maximum yield strength of a single crystal of copper be calculated under tension?

When a material is subjected to external forces, such as tension, the atoms within the crystal lattice experience shear stresses. The critical resolved shear stress (CRSS) represents the stress required to initiate plastic deformation in a crystal. In the case of copper (Cu), the given CRSS is 0.48 MPa (70 psi).

To determine the maximum possible yield strength, we can utilize the relationship between the CRSS and the yield strength. In single crystal materials, the yield strength (σ_y) is related to the CRSS (τ) by the formula: σ_y = k * τ, where k is a constant that depends on the crystal structure and deformation mechanism.

Assuming a perfect single crystal, the maximum yield strength can be calculated by substituting the given CRSS value into the equation. However, it's important to note that this calculation provides an upper limit and assumes ideal conditions without any defects or dislocations present.

A homeowner consumes 260 kWh of energy in July when the family is on vacation most of the time. Determine the average cost per kWh for the month using the following residential rate schedule: Base monthly charge of $10.00. First 100 kWh per month at 16 cents/kWh. Next 200 kWh per month at 10 cents/kWh. Over 300 kWh per month at 6 cents/kWh.

Answers

Answer:

16.2 cents

Explanation:

Given that a homeowner consumes 260 kWh of energy in July when the family is on vacation most of the time.

Where Base monthly charge of $10.00. First 100 kWh per month at 16 cents/kWh. Next 200 kWh per month at 10 cents/kWh. Over 300 kWh per month at 6 cents/kWh.

For the first 100 kWh:

16 cent × 100 = 1600 cents = 16 dollars

Since 1 dollar = 100 cents

For the remaining energy:

260 - 100 = 160 kwh

10 cents × 160 = 1600 cents = 16 dollars

The total cost = 10 + 16 + 16 = 42 dollars

Note that the base monthly of 10 dollars is added.

The cost of 260 kWh of energy consumption in July is 42 dollars

To determine the average cost per kWh for the month of July, divide the total cost by the total energy consumed.

That is, 42 / 260 = 0.1615 dollars

Convert it to cents by multiplying the result by 100.

0.1615 × 100 = 16.15 cents

Approximately 16.2 cents

A milling machine is used to process an automobile part. The processing time per part is 4 minutes. After producing 190 units of the part, the milling machine requires a 34 minute maintenance process. Demand for the part is 12 units per hour.

What is the maximum inventory of a part (in units)?

Answers

The maximum inventory of the part is limited to 3 units to match the demand rate of 12 units per hour.

To determine the maximum inventory of a part, we need to consider the processing time, maintenance time, and the demand rate. The processing time per part is given as 4 minutes, and after producing 190 units, a 34-minute maintenance process is required. The demand for the part is 12 units per hour.

First, let's calculate the total time required to produce 190 units:

Total production time = (Processing time per part) * (Number of units produced)

Total production time = 4 minutes * 190 units

Total production time = 760 minutes

Next, let's calculate the total time available for production:

Total time available = (Total production time) + (Maintenance time)

Total time available = 760 minutes + 34 minutes

Total time available = 794 minutes

Now, let's calculate the maximum inventory:

Maximum inventory = (Total time available) / (Time required to produce one unit)

Maximum inventory = 794 minutes / (4 minutes per unit)

Maximum inventory = 198.5 units

Since we cannot have fractional units of inventory, the maximum inventory of the part is rounded down to the nearest whole number, which is 198 units. However, since the demand for the part is 12 units per hour, we need to consider the time it takes to produce one unit. With a processing time of 4 minutes per unit, it takes 12 minutes to produce 3 units. Therefore, the maximum inventory of the part is limited to 3 units to match the demand rate of 12 units per hour.

Two kg of a two phase liquid vapor mixture of carbon dioxide(co2) exists at a - 40C in a 0.05 tank

Answers

The question is incomplete. Here is the complete question.

Two kg of a two phase liquid vapor mixture of carbon dioxide (CO₂) exists at -40°C in a 0.05m³ tank. Determine the quality of the mixture, if the values of specific volume for saturated liquid and saturated vapor CO₂ at -40°C are \(v_{f}\) = 0.896 x 10⁻³m³/kg and \(v_{g}=\) 3.824 x 10⁻²m³/kg, respectively.

Answer: x = 1

Explanation: In a phase change of a pure substance, at determined pressure and temperature, the substance exists in two different phases: saturated liquid and saturated vapor.

Quality (x) is the ratio of saturated vapor in the mixture and can be written as:

\(x=\frac{m_{vapor}}{m_{liquid}+m_{vapor}}\)

It has value between 0 and 1: x = 0 for saturated liquid and x = 1 for saturated vapor.

When related with volumes, quality is rearranged as:

\(x=\frac{v-v_{f}}{v_{g}-v_{f}}\)

Solving for x:

\(x=\frac{0.05-0.896.10^{-3}}{3.824.10^{-2}-0.896.10^{-3}}\)

\(x=\frac{0.049104}{0.037344}\)

x = 1.3

Quality of mixture of carbon dioxide is x = 1, which means it's for saturated vapor.

A resistor of resistance R and an uncharged capacitor of capacitance C is connected in series with an ideal battery of EMF E.At time t, what is the rate at which thermal energy is appearing in the resistor? Express your answer in terms of the variables given.

Answers

The rate at which thermal energy is appearing in the resistor at time t can be found using the formula: P = I^2 * R, where P is the power, I is the current flowing through the circuit, and R is the resistance of the resistor. To find the current, we can use the equation for the charge on a capacitor as it charges up: Q = C * V, where Q is the charge on the capacitor, C is the capacitance, and V is the voltage across the capacitor.

Since the capacitor starts uncharged, the initial voltage across it is zero. As the capacitor charges up, the voltage across it will increase, but the voltage across the resistor will be equal to the battery's EMF E. Therefore, the current flowing through the circuit at time t can be found using Ohm's Law: I = E / (R + (1/C) * Q). Substituting Q = C * V, we get I = E / (R + (1/C) * C * V). Since V = Q/C, we get I = E / (R + V).

To find V, we can use the equation for the voltage across a charging capacitor: V = E * (1 - e^(-t / (R * C))). Substituting this into the expression for I, we get:

I = E / (R + E * (1 - e^(-t / (R * C))) / C)

Now we can find the power dissipated in the resistor at time t:

P = I^2 * R = (E^2 * R) / ((R + E * (1 - e^(-t / (R * C))) / C)^2)

So the rate at which thermal energy is appearing in the resistor at time t is (E^2 * R) / ((R + E * (1 - e^(-t / (R * C))) / C)^2), expressed in terms of the given variables resistance R, capacitance C, and EMF E.

Polarization: Unpolarized light passes through three ideal polarizing filters. The first filter is oriented with a horizontal transmission axis, the second one has its transmission axis at 30° from the horizontal, and the third filter has a vertical transmission axis. What percent of the light gets through this combination?

Answers

Answer:

the percentage of light that gets through this combination is 9.38

Explanation:

Given the data in the question;

Let us represent the incident unpolarized light with \(I_0\).

So, the amount of light intensity passing through the first polarizer will be;

\(I_1\) = \(I_0\) / 2 ------ let this be equation 1

An the amount of light intensity passing through the second polarizer will be;

\(I_2\) = \(I_1\)cos²θ

given that; the second one has its transmission axis at 30°

so, we substitute;

\(I_2\) = \(I_1\) × cos²( 30° )

\(I_2\) = \(I_1\) × 0.75

\(I_2\) = 0.75\(I_1\)

from equation; \(I_1\) = \(I_0\) / 2

\(I_2\) = 0.75( \(I_0\) / 2 )

\(I_2\) = 0.375\(I_0\) .

Now, the amount of light intensity passing through the third polarizer will be;

\(I_3\) = \(I_2\)cos² ( 90° - 30° )

\(I_3\) = \(I_2\) × cos²( 60° )

\(I_3\) = \(I_2\)  × 0.25

we substitute

\(I_3\) = 0.375\(I_0\)  × 0.25

\(I_3\) = 0.09375\(I_0\)

∴ \(I_3\)/\(I_0\) × 100 = 0.09375 × 100

9.38%

Therefore, the percentage of light that gets through this combination is 9.38

Answers

Answer:

a) the minimum sampling rate is 6 kHz

b) the minimum numbers of required samples are 120

c) the minimum length of the analog signal is 0.02 s

Explanation:

Given the data in the question;

(a) the minimum sampling rate;

band width of analog signal xₐ(t) is;

bandwidth B = 3kHz

Now, according to sampling theorem, minimum sampling rate F\(_s\) must be twice the bandwidth of the signal.

so

F\(_s\) = 2B

F\(_s\) = 2( 3 kHz )

F\(_s\) = 6 kHz

Therefore, the minimum sampling rate is 6 kHz

(b) the minimum number of required samples;

Let L represent the minimum number of samples required,

given that; required resolution of the spectrum of the signal is less than or equal to 50 Hz

F\(_s\)/L ≤ 50

L ≥ F\(_s\)/50

L ≥ ( 6 × 1000 Hz ) / 50

L ≥ 6000 / 50

L ≥ 120

Therefore, the minimum numbers of required samples are 120

(c) the minimum length of the analog signal record(in seconds).

minimum number of samples required is 120

T = L /  F\(_s\)

T = 120 / ( 6 × 1000 Hz )

T = 120 / 6000

T = 0.02 s

Therefore, the minimum length of the analog signal is 0.02 s

Then, the assembler takes the assembly code and converts it bit-by-bit to the corresponding bit code.Imagine that there is a table with a line for each potential assembly statement. The statement itself is next on each line, followed by the corresponding bits that the computer can understand on the right.Even so, assemblers also have supplementary features like macros and other features, but the aforementioned functionality is their primary functionality.Binary is just a numbering scheme to programmers. For instance, base2 contains some 0s and 1s. These binary numbers are used by all computers. They interpret the instructions as a list of these numbers. They are not affected by the human-generated code, which is typically produced using a high-level programming language like Python, Java, and others.It is obvious that machine instructions in computers are not really human-readable - most people cannot determine the operational difference between 100010001... and 010001000...  by simply looking at a binary or hex representation of the instruction bytes. Simply put, these instructions are machine codes.For instance, in the x86-16 architecture, the following instruction is used as the machine code for loading a value into a register: With a 2-bit addressing mode field and a 3-bit base register, the formula 8B 0E 34 12 denotes mov r16, r/m16, and which register the destination is (in this case, CX).

Actually, it is simple to translate it to binary, and you have already mentioned that it is "10001011000011100011010000010010. Just like a string of ASCII 0 and 1 but more condensed, HEX is a text serialization format for binary numbers.Such binray/HEX instructions are readable by humans thanks to assembly, which is a higher level programming language than machine code.

Plot y(n) which is achieved by y(n) = x(n) ⋆ h(n).x(n) = {1, 1, 1, 1, 1}h(n) = {1, 1, 1}By applying convolution, we get y (n) = x(n) ⋆ h(n) = {1, 2, 3, 3, 3, 2, 1}(b) Solve the above problem analytically by hand and determine if the two outputs are the same.

x(n) = {1, 1, 1, 1, 1}h(n) = {1, 1, 1}y(n) = x(n) ⋆ h(n)So, $$y(n) = \sum_{k=-\infty}^{\infty} x(k)h(n-k)$$The non-zero terms in the summation will be when k = 0, 1, 2, 3, 4. Then,$$y(n) = \sum_{k=0}^{4} x(k)h(n-k)$$$$y(n) = \sum_{k=0}^{4} h(k) x(n-k)$$Substituting the given values of x(n) and h(n), we have $$y(n) = (1 * 1) + (1 * 1) + (1 * 1) + (1 * 1) + (1 * 1)$$$$y(n) = 1 + 1 + 1 + 1 + 1$$$$y(n) = 5$$The first and the last samples in y(n) occur when h(n) overlaps with the endpoints of x(n), which are 0 and 4. Hence, the duration of y(n) is 5 samples.

The convolution output of x(n) and h(n) matches with the result obtained in the above solution.

(a)Suppose x(n) = {1, 1, 1, 1, 1} and h(n) = {1, 1, 1}, where the underline symbol indicates the time index 0. Plot y(n) which is achieved by y(n) = x(n) ⋆ h(n). To calculate the convolution between two signals, we utilize MATLAB's conv function.

Using the following code, we may easily plot the output clear all; close all; %clearing command window and work spa = [1 1 1 1 1] = [1 1 1] = conv(xn,hn);%convolution of x and h Solve the above problem analytically by hand and determine if the two outputs are the same.

The mathematical computation of convolution of x(n) and h(n) is represented by the following formula:\[y(n)=x(n)*h(n)=\sum (k)h(n-k)\]On substituting the given values of x(n) and h(n), we get,\[y(n)=x(n)*h(n)=\sum_{k=-\i}x(k)h(n-k)\]\[y(n)=(1)(1)+(1)(1)+(1)(1)+(1)(1)+(1)(1)\]\[y(n)=5\]Therefore, both the results are same.

A shaft of a circular cross section is supported by two housings at B and C. The shaft
is subjected to static loads: concentrated force N applied by gear D and an applied torque T. The yielding strength of the shaft is Sy, and the diameter of the shaft is d. For circular cross sections, | = nd*/64, J = md*/32. The length of the shaft is L. Transverse shear stress is ignored here.

1) Draw the bending moment diagram of the shaft. Specify the location of the weakest (most dangerous) cross section A on bending moment diagram.

2) Draw the weakest point(s) on cross section A.

3) Determine the von-Mises stress at the weakest point(s).

4) Determine the factor of safety n based on Distortion Energy Theory.

Answers

Answer:

1) The bending moment diagram of the shaft is shown in Figure 1. The weakest cross section A is located at the point where the bending moment is maximum.

2) The weakest point on cross section A is located at the point where the bending moment is maximum.

3) The von-Mises stress at the weakest point is given by:

σ = M/I

where M is the bending moment and I is the moment of inertia of the cross section.

4) The factor of safety n is given by:

n = Sy/σ

where Sy is the yield strength of the shaft and σ is the von-Mises stress at the weakest point.

A beaker is filled to the 500 ml mark with alcohol. What increase in volume (in ml) the beaker contain when the temperature changes from 5°C to 30°C? (Neglect the expansion of the beaker, evaporation of alcohol and absorption of water vapor by alcohol.) C°, Palcohol = 1.12 x 104/ °C

Answers

Answer:

1.4 mL

Explanation:

Given that:

volume of alcohol \(V_0\) = 500

Temperature change ΔT = (30° - 5°)C

=25° C

\(\beta_{ alcohol }= 1.12 \times 10^{-4} / ^0C\)

The increase in volume ΔV =  \(\alpha \times V_o \times \Delta T\)

\(= 500 \times 1.12 \times 10^{-4} / ^0 C\times 25^0 C\)

= 1.4 mL
