Answer:

18.75in

Explanation:

Modulus of elasticity = Stress/Strain

Since stress = Force/Area

Given

Force = 1000lb

Area = 0.75sqin

Stress = 1000/0.75

Stress = 1333.33lbsqin

Strain

Strain = Stress/Modulus of elasticity

Strain = 1333.33/5,000,000

Strain = 0.0002667

Also

Strain = extension/original length

extension = 0.005in

Original length = extension/strain

Original length = 0.005/0.0002667

Original length = 18.75in

Hence the original length of the rectangular bar is 18.75in

Answer:

To* = 1074.9k  ( stagnation temperature )

Po* = 0.467 MPa ( stagnation pressure )

Explanation:

Given data:

Po1 = 1.6 MPa

To = 430°c + 273 = 703 k

Mach number at inlet ( M1 )= 3

Mach number at exit ( M2 )  = 1

at M1 = 3

To1 / To* = 0.65398  ( value gotten from Rayleigh's flow gas tables )

therefore  To* = 1074.9k

also

Po1 / Po* = 3.42445 ( value gotten from Rayleigh's flow gas tables )

therefore  Po* = 0.467 MPa

at M2 = 1

To2 = To* = 1074.9k

Po2 = Po* = 0.467 MPa

using both Rayleigh's flow table and Isentropic Tables the values of stagnation temperature and stagnation pressure are the same at the exit

Answer:

a) \(L = 1.5\)

\(L_q = 0.9\)

\(W = \dfrac{1 }{8 } \, hour\)

\(W_q = \dfrac{3}{40 } \, hour\)

\(P = \dfrac{3}{5 }\)

b) The new backacter should be recommended

c) The additional backacter should not be deployed

Explanation:

a) The required parameters are;

L = The number of customers available

\(L = \dfrac{\lambda }{\mu -\lambda }\)

μ = Service rate

\(L_q\) = The number of customers waiting in line

\(L_q = p\times L\)

W = The time spent waiting including being served

\(W = \dfrac{1 }{\mu -\lambda }\)

\(W_q\) = The time spent waiting in line

\(W_q = P \times W\)

P = The system utilization

\(P = \dfrac{\lambda }{\mu }\)

From the information given;

λ = 12 trucks/hour

μ = 3 min/truck = 60/3 truck/hour = 20 truck/hour

Plugging in the above values, we have;

\(L = \dfrac{12 }{20 -12 } = \dfrac{12 }{8 } = 1.5\)

\(P = \dfrac{12 }{20 } = \dfrac{3}{5 }\)

\(L_q = \dfrac{3}{5 } \times \dfrac{3}{2 } = \dfrac{9}{10 } = 0.9\)

\(W = \dfrac{1 }{20 -12 } = \dfrac{1 }{8 } \ hour\)

\(W_q = \dfrac{3}{5 } \times \dfrac{1}{8 } = \dfrac{3}{40 } \, hour\)

(b) The service rate with the new backacter = 1.5 minutes/truck which is thus;

μ = 60/1.5 trucks/hour = 40 trucks/hour

\(P = \dfrac{12 }{40 } = \dfrac{3}{10}\)

\(W = \dfrac{1 }{40 -12 } = \dfrac{1 }{38 } \, hour\)

\(W_q = \dfrac{3}{10 } \times \dfrac{1}{38 } = \dfrac{3}{380 } \, hour\)

λ = 12 trucks/hour

Total cost = \(mC_s + \lambda WC_w\)

m = 1

\(C_s\) = GH¢ = 1300

\(C_w\) = 400

Total cost with the old backacter is given as follows;

\(1 \times 1000 + 12 \times \dfrac{1}{8} \times 400 = \$ 1,600.00\)

Total cost with the new backacter is given as follows;

\(1 \times 1300 + 12 \times \dfrac{1}{38} \times 400 = \$ 1,426.32\)

The new backacter will reduce the total costs, therefore, the new backacter is recommended.

c)

Here μ = 3 min/ 2 trucks = 2×60/3 truck/hour = 40 truck/hour

\(\therefore W = \dfrac{1 }{40 -12 } = \dfrac{1 }{38 } \, hour\)

Total cost with the one backacter is given as follows;

\(1 \times 1000 + 12 \times \dfrac{1}{8} \times 400 = \$ 1,600.00\)

Total cost with two backacters is given as follows;

\(2 \times 1000 + 12 \times \dfrac{1}{38} \times 400 = \$ 2,126.32\)

The additional backacter will increase the total costs, therefore, it should not be deployed.

Boost converters can also supply power to smaller-scale equipment, including portable lighting systems.

A boost converter can increase the voltage from a single 1.5 V alkaline cell to provide the lamp with the 3.3 V that a white LED generally needs to emit light. High-frequency power conversion circuits known as DC-DC converters use inductors, transformers, and capacitors to reduce switching noise and produce regulated DC voltages. Even with fluctuating input voltages and output currents, closed feedback loops maintain constant voltage output. To "step-up" an input voltage to a higher level, needed by a load, the boost converter is utilized. By holding energy in an inductor and delivering it to the load at a greater voltage, this special feature is made possible.

Isotopes are two or more different types of atoms that share the same atomic number and position in the periodic table (and, therefore, belong to the same chemical element), but differ in their nucleon numbers (mass numbers) because they have varying numbers of neutrons in their nuclei.

Despite having essentially the same chemical characteristics, each isotope of a given element has a unique atomic mass and set of physical characteristics. The word "isotope" derives from the Greek words "isos" and "topos," both of which mean "the same place."

As a result, the name "isotope" refers to the fact that different isotopes of the same element occupy the same position on the periodic table. In 1913, British chemist Frederick Soddy received a suggestion from Scottish doctor and writer Margaret Todd, who coined the term.

Explanation:

If a researcher thought cohort effects would be a problem in their study, the researcher should avoid using a cross-sectional design.  The correct answer is A.

The cross-sectional design is a research design in which data is collected from participants at one point in time. The cross-sectional design is inappropriate for researching cohort effects since it focuses on collecting data from different individuals at a single point in time instead of following a particular cohort over time.

The longitudinal design is a research design that follows a single group of individuals over time. The longitudinal design is a suitable research design for studying cohort effects because it focuses on tracking the development and behavior of a particular cohort over time.  Experimental and correlational designs are used in various types of research studies, such as studying the relationship between variables, assessing the efficacy of interventions, and identifying causal relationships. These designs may or may not be appropriate for studying cohort effects.

Therefore, the correct answer is A.

If you type the D. su command at the Linux shell, you are asked for the root password. If you successfully supply it, you will then have root privileges.

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.

An electric spark is used in a gasoline engine's ignition system to start the fuel-air combination, which burns in the cylinders to create the motive force.

A storage battery, an induction coil, a device to timing high-voltage discharges from the induction coil, a distributor, and a set of spark plugs are the essential parts of the ignition system. The mechanism converts the low voltage electric current from the storage battery, which is typically 12 volts, to high voltage (some 40,000 volts).

To determine the force in members GF, GD, and CD of the truss, we need to use the method of joints. We start by analyzing joint A, which is connected to members AB, AC, and AD. Since joint A is in equilibrium, the forces acting on it must sum up to zero.

Using the given loads P1, P2, and P3, we can write the following equations:

∑Fx = 0: -GF + P1 cos(60°) + P2 cos(45°) = 0
∑Fy = 0: GD - P1 sin(60°) - P2 sin(45°) - P3 = 0
∑Fz = 0: -CD - P2 cos(45°) sin(60°) = 0

Solving these equations simultaneously, we get:

GF ≈ 16.37 kN (tension)
GD ≈ 23.34 kN (compression)
CD ≈ 20.59 kN (tension)

Therefore, the force in member GF is 16.37 kN in tension, the force in member GD is 23.34 kN in compression, and the force in member CD is 20.59 kN in tension.
