The solution of given relations are σ = 1.897 ksi (using the kilo- prefix), σ = 0.397 ksi (using the kilo- prefix).

To solve the given relations and apply the rules for rounding and prefix selection, we'll follow the steps for each relation:

(a)

Given:

σ = M/Z

σ = 1770 lbf⋅in / 0.934 in^3

M = 1770 lbf⋅in

Z = 0.934 in^3

To round the result to three digits and choose prefixes, we'll divide the values by appropriate factors until we have no more than four digits to the left of the decimal point:

σ = (1770 / 0.934) lbf⋅in / \(in^3\)

σ = 1896.99 \(lbf/in^2\)

σ = 1.897 ksi (using the kilo- prefix)

(b)

Given:

σ = F/A

σ = 9440 lbf / 23.8 \(in^2\)

F = 9440 lbf

A = 23.8 \(in^2\)

σ = (9440 / 23.8) lbf / \(in^2\)

σ = 396.64 lbf/\(in^2\)

σ = 0.397 ksi (using the kilo- prefix)

(c)

Given:

σ = F *l^3 / 3EI

σ = (270 lbf) * (31.5 in)^3 / (3 * 30 Mpsi * 0.154 in^4)

F = 270 lbf

l = 31.5 in

E = 30 Mpsi

I = 0.154 in^4

σ = (270 * \(31.5^3\)) / (3 * 30 * 0.154) psi

σ = 34682.86 psi

σ = 34.7 ksi (using the kilo- prefix)

(d)

Given:

θ = T*l / GJ

θ = (9740 lbf⋅in) * (9.85 in) / (11.3 Mpsi * 1.00 in)

T = 9740 lbf⋅in

l = 9.85 in

G = 11.3 Mpsi

J = 1.00 in

θ = (9740 * 9.85) / (11.3 * 1.00) rad

θ = 8507.82 rad

θ = 8508 rad (rounding to three digits)

Thus, (a) σ = 1.897 ksi, (b) σ = 0.397 ksi, (c) σ = 34.7 ksi, (d) θ = 8508 rad.

The "su" command stands for "substitute user" and is used in Linux to switch to another user account, typically the superuser account known as "root." When you execute the "su" command, you are prompted to enter the root password. If the password is correct, the system grants you root privileges, allowing you to perform administrative tasks and access system files and directories that are restricted to regular users.

Using the "su" command is a common way for authorized users to temporarily assume superuser privileges to carry out administrative tasks that require elevated permissions. It provides a way to execute commands or perform actions that regular users are restricted from doing.

It's important to exercise caution when using root privileges since they grant extensive control over the system. Misuse or accidental changes made as the root user can have significant consequences, including system instability or security vulnerabilities. Therefore, it is recommended to use root privileges judiciously and only when necessary to ensure the security and stability of the Linux system.

The Equivalent Service Life (ESL) of the injection molding system is determined to be 3 years, and the respective Annual Worth (AW) value of the system is calculated.

To determine the Equivalent Service Life (ESL) and Annual Worth (AW) value of the injection molding system, we need to calculate the Present Worth (PW) of costs and salvage value over the system's maximum useful life of 5 years. The first cost of $180,000 and the salvage value of 25% of the first cost ($45,000) are considered.

The annual operating cost of $95,000 in years 1 and 2, increasing by $4,500 per year thereafter, is converted to an equivalent uniform annual cost (EUAC) using the given MARR (12% per year). This EUAC is then added to the salvage value to obtain the PW.

By comparing the PW values at different service lives (1 to 5 years), the ESL is determined to be 3 years, which corresponds to the minimum PW value. The AW value is then calculated by dividing the PW by the ESL.

By considering the MARR, the cash flows over the system's life, and the salvage value, the ESL and AW value of the injection molding system can be determined, providing insights into the economic performance of the system over time.

QDFF in electrical engineering stands for "Quasi-Delay Flip-Flop."

It is a type of digital circuit used in synchronous systems to store binary data. A QDFF can change its output value based on the input value and the control signal, typically a clock signal. Here's a step-by-step explanation of its operation:

1. The QDFF receives an input value (0 or 1) and a clock signal.
2. When the clock signal changes from a low voltage to a high voltage (rising edge), the QDFF checks the input value.
3. The QDFF stores the input value internally and sets its output value to match the input value.
4. The output value remains unchanged until the next rising edge of the clock signal, when the QDFF checks the input value again and updates the output value accordingly.

In summary, QDFF is a digital circuit used in electrical engineering to store binary data based on input values and a control signal.

The student group could use a lever as a simple machine to lift the 50-gram weight.

In order to lift the 50-gram weight 2 inches in the air, the group should use a lever with a mechanical advantage of 5. This is because the toy car is 10 grams, and the weight is 50 grams, so the ratio of the output force to the input force is 50/10 = 5. The lever should have a fulcrum placed closer to the weight and a longer arm for the toy car to exert force on. This configuration will enable the toy car to lift the 50-gram weight with less effort.

The critical-section problem is well-described algorithmically in Peterson's solution, which also highlights some of the challenges in creating software that satisfies the conditions of mutual exclusion, progress, and constrained waiting. Mutual exclusion is intact.

In an operating system, a code segment that atomically accesses shared variables or resources ensures that no other code or process is concurrently accessing them. Access to the shared resource or variable is permitted by the entry section code block, and access to the shared resource or variable is terminated by the exit section code. The vital portion of code is the area of the program where processes can access and modify shared resources, such as files and common variables. Any process can be stopped mid-execution since processes run concurrently. Instruction sets known as critical sections are those that cannot be interleaved with other threads. When two threads share a global variable, this is a straightforward illustration of a key section.

Given Data:

Internal pressure of tank = 90 psi

Internal diameter of tank = 22 in

Wall thickness = 0.25 in

Stress components are to be determined at point A and maximum shear is to be calculated.

Volume Element:

The volume element at point A has six faces and the stress components are acting on these faces. The stress components acting at point A need to be calculated.

Stress Components:

Consider the cylinder element shown below:

The stress acting on the horizontal and vertical faces is called longitudinal stress and the stress acting on the oblique faces is called shear stress.

Longitudinal Stress:

Longitudinal stress is given by the formula:

σL = (P x D) / (4t)

Where,

P is the internal pressure of the tank

D is the internal diameter of the tank

t is the thickness of the tank

Substituting the values in the formula, we get:

σL = (90 x 22) / (4 x 0.25)

σL = 1980 psi

Shear Stress:

The shear stress is given by the formula:

τ = σ / 2

Where,

σ is the longitudinal stress

Substituting the value of σ in the formula, we get:

τ = 1980 / 2

τ = 990 psi

The shear stress acting on the oblique faces is 990 psi and the maximum shear stress acting on the element is 990 psi. Hence, the maximum shear stress that this material would experience is 990 psi.

Option C. The correct statement about the static pressure p₂ relative to p₁ and the velocity V₂ relative to V₁ along the streamline down the center of the pipe is p₂ > p₁ and V₂ < V₁.

When fluid flows without friction through a horizontal pipe and enters a section where the cross-sectional area is smaller, the static pressure at the smaller area decreases relative to the static pressure at the larger area, whereas the velocity increases. Therefore, the correct statement about the static pressure p₂ relative to p₁ and the velocity V₂ relative to V₁ along the streamline down the center of the pipe is p₂ > p₁ and V₂ < V₁.

This is because the mass flow rate is conserved across any cross-section of the pipe, and this leads to an increase in fluid speed as the cross-sectional area decreases (and vice versa). As a result, the fluid experiences an increase in velocity head and a decrease in pressure head as it moves from the larger area to the smaller area.

Therefore the correct option is C.
