Discuss how the configuration of software will
help a given user perform their tasks.

Answer:

A) L = 0.388 μm

B) D = 3.78 mm

Explanation:

We are given;

Characteristics impedance; Z_o = 75 ohms

Nominal capacitance; C = 69pF/m = 69 × 10^(-12) F/m

dielectric constant; k = 2.23

Inner diameter of conductor; d = 0.584 mm

A) Now formula for Characteristics impedance is given as;

Z_o = √(L/C)

Where L is the inductance per metre.

Making L the subject, we have;

L = (Z_o)²C

L = 75² × 69 × 10^(-12)

L = 0.388 × 10^(-6) m

L = 0.388 μm

B) To get the outer diameter, we will use the formula;

Z_o = (138/√k) log(D/d)

Where;

D is outer diameter.

Thus, Plugging in the relevant values;

75 = (138/√2.23) × log (D/0.584)

log (D/0.584) = 0.81158611538

(D/0.584) = 10^(0.81158611538)

D/0.584 = 6.48016576435

D = 6.48016576435 × 0.584

D = 3.78 mm

Answer:

To find the stress you need to know the applied load. Without that information, it is not possible to determine the axial stress in each of the three rods.

Explanation:

To determine the axial stress in each of the three rods, you would need to know the applied load and the cross-sectional area of each rod. The formula for axial stress is:

Stress (σ) = Load (F) / Area (A)

The area of a rod can be determined using the formula:

Area = π * (diameter/2)^2

Where diameter is the diameter of the rod in inches.

So,

For rod 1(aluminum rod)

Area = π * (2.00/2)^2 = 3.14 in^2

For rod 2(brass rod)

Area = π * (1.50/2)^2 = 1.77 in^2

For rod 3(steel rod)

Area = π * (3.00/2)^2 = 7.07 in^2

To find the stress you need to know the applied load. Without that information, it is not possible to determine the axial stress in each of the three rods.

Answer:D

Explanation:

Option D is correct. Balancing the crankshaft is NOT one of the functions of a flywheel.

A flywheel is part of an automobile. It is a heavy wheel that is attached to a rotating shaft of an automobile. Since there may be the presence of large forces within an automobile structure, the presence of a flywheel helps to balance the force evenly across it.  

Some of the functions of the flywheel are but are not limited to help in transferring power to the transmission, engaging the starter, and smoothing out of power pulses.

Hence based on the explanation above, balancing the crankshaft is NOT one of the function of a flywheel.

Answer:

C. Both A and B

Explanation:

Technician B is correct because the technician highlighted valid reasons why draining the compressed air systems is important.

For example, since this system helps to absorb moisture or oil from storage areas they thus need to be drained periodically in other to allow for more absorption space.

Also, the reasons mentioned by Technician A are of course correct because it is generally believed that the application of lubricants such as oil helps to reduce wear and tear.

Before employees perform any servicing or maintenance where the unexpected energization or start-up of the machine or equipment or release of stored energy could cause injury, it shall be used to ensure that the machine or equipment is stopped, isolated from all potentially hazardous energy sources, and locked out.

Title 29 Code of Federal Regulations (CFR) Part 1910.147, the OSHA standard for The Control of Hazardous Energy (Lockout/Tagout), covers the practices and procedures required to shut down machinery or equipment in order to prevent the release of hazardous energy while workers perform servicing and maintenance.

This procedure must be followed to guarantee that all energy sources that could be hazardous have been shut off and that the machinery, apparatus, or system that has to be maintained has been rendered inoperable by lockout or similar measures.

Answer:

[FIRST 2 SO FAR]

Explanation:

1. The cell and the transistor would be considered to be the lowest level of abstraction. This is because they are the smallest, basic building blocks that make up these structures.

The cell makes up the parts of the body and the transistors make up the computer. The cells take in nutrients from food, converts the nutrients into energy, and carry out specialized functions. Cells move around to convert chemical energy into mechanical energy, allowing the body to move. The transistors are like switches that turn on and off electric current (by controlling the movement of electrons, either stopping or starting the current). They store and move data from one place to another, allowing the computer or device to work.

These two structures are both the smallest part that makes up the main structure. They allow the larger structure that they are contained in to function by doing small tasks/activities in the structure.

2. The Tissue and Logic Gate are a lower-level abstraction because the are composed of smaller structures.

Tissues are groups of cells that perform one or more specific functions. Tissues (enforced by the cells) can control the movement of information that is spread through the surface of the body, protect and support organs, and allow entire body movement. Logic gates are the basic building blocks of digital system that can have more than one input and only one output. These input and output functions are determined by using logic, with the gates being named And, Or, and Not.

The two structures are similar because they allow the movement of something to flow through the bigger structure, allowing the structure to function. Logic Gates control the actions of the transistors by taking in multiple inputs, then uses logic to tell the transistor to turn on or off an electric current.

The minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.

To calculate the minimum pressure at which the water-supplying pump must operate, we need to use the formula for the volumetric flow rate of a fluid:

Q = A * v

where,

Q =the flow rate

A = the cross-sectional area of the hole

v = the velocity of the fluid.

We can use this formula to determine the velocity of the water, and then use the Bernoulli equation to determine the minimum pressure.

From the question:

ṁ=0.05 kg/s

ρ= 996 kg/m

d= 0.02 cm

Calculating the area of the hole:

A = (π/4) * (d²)

where,

d is the diameter of the hole, and pi is approximately 3.14.

d = 0.02 cm = 0.0002 m

A = (3.14/4) * (0.0002 m)² = 1.57 x 10⁻⁷ m²

Using the mass flow rate to calculate the velocity of water:

Q = ṁ / ρ

where,

Q = the volumetric flow rate

ṁ = the mass flow rate

ρ = the density of water.

Q = (0.05 kg/s) / (996 kg/m³)

Q = 5 x 10⁻⁵ m³/s

Using the area of the hole to find the velocity of water

v = Q / A

v = (5 x 10⁻⁵ m³/s) / (1.57 x 10⁻⁷m²)

v = 318.8 m/s

Using the Bernoulli equation to find the pressure:

P = Patm + (1/2) * ρ * v²

where,

P = the pressure

Patm = the atmospheric pressure

ρ =the density of water

v = the velocity of the water.

P = Patm + (1/2) * (996 kg/m³) * (318.8 m/s)²

Hence, the minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.

Answer:

R = 20Ω

L = 0.1 H

C = 1 × 10⁻⁵ F

Explanation:

Given the data in the question;

Vs = 10∠30°V   { peak value }

V"s\(_{rms\) = 10/√2 ∠30° V

resonance freq w₀ = 10³ rad/s

Average Power at resonance Power\(_{avg\)  = 2.5 W

Q = 5

values of R, L, and C = ?

We know that;

Power\(_{avg\) = |V"s\(_{rms\)|² / R

{ resonance circuit is purely resistive }

we substitute

2.5 = (10/√2)² × 1/R

2.5 = 50 × 1/R

R = 50 / 2.5

R = 20Ω

We also know that;

Q = w₀L / R

we substitute

5 = ( 10³ × L ) / 20

5 × 20 = 10³ × L

100 = 10³ × L

L = 100 / 10³

L = 0.1 H

Also;

w₀ = 1 / √LC

square both side

w₀² = 1 / LC

w₀²LC = 1

C = 1 / w₀²L

we substitute

C = 1 / [ (10³)² × 0.1 ]

C = 1 / [ 1000000 × 0.1 ]

C = 1 / [ 100000 ]

C = 0.00001 ≈ 1 × 10⁻⁵ F

Therefore;

R = 20Ω

L = 0.1 H

C = 1 × 10⁻⁵ F
