Self induction and Mutual induction

If the current through the coil changes, the flux through the coil changes and an emf is induced. Since the emf is induced in the coil due to its own field, it is called self–induced emf and the phenomenon is called self–induction.

Answer:

Self induced EMF is the electro-motive force that is generated due to change in flux in the coil caused by the change in current in the same coil.

Answer and Explanation:

The coefficient of determination also called "goodness of fit" or R-squared(R²) is used in statistical measurements to understand the relationship between two variables such that changes in one variable affects the other. The level of relationship or the degree to which one affects the other is measured by 0 to 1 whereby 0 means no relationship at all and 1 means one totally affects the other while figures in between such 0.40 would mean one variable affects 40% of the other variable.

In making a decision as an engineer while using the coefficient of determination, one would try to understand the relationship between variables under consideration and make decisions based on figures obtained from calculating coefficient of determination. In other words when there is a 0 coefficient then there is no relationship between variables and an engineer would make his decisions with this in mind and vice versa.

Five broken wires in one strand or ten broken wires spread at random were laid in a rope.

If the total number of visible broken wires in any length of eight diameters exceeds 10% of the total number of wires, or if the rope exhibits other symptoms of excessive wear, corrosion, or defect, the rope may not be utilised for the vessel's cargo gear. Special attention must be paid to the condition of wire rope portions that are close to terminal connections, are subject to anomalous wear, and are not typically exposed for inspection.

The ratio of shear strength of the clay in vertical direction to that in horizontal direction is 1.41.

The force that can cause an object to rotate along an axis is measured as torque. Similar to how force accelerates an item in linear kinematics, torque accelerates an object in an angular direction.

The apparent shear stress of the soil can be calculated using the following formula:

τ = T/(2πLW)

Where τ is the apparent shear stress, T is the torque at failure, L is the length of the vane, and W is the width of the vane.

For the first test with the vane of length 150mm and diameter 60mm:

τ1 = 46/(2π × 0.15 × 0.06) = 666.67 kPa

For the second test with the vane of length 200mm and diameter 90mm:

τ2 = 138/(2π × 0.2 × 0.09) = 402.23 kPa

To calculate the ratio of shear strength of the clay in vertical direction to that in horizontal direction, we can use the formula:

tan φ = (τv - σ)/τh

Where φ is the angle of internal friction, τv is the shear strength in the vertical direction, τh is the shear strength in the horizontal direction, and σ is the normal stress.

Assuming that the normal stress is the same in both directions, we can rearrange the formula to get:

τv/τh = tan φ + 1

To find the angle of internal friction, we can use the average of the two apparent shear stresses:

φ = (1/2) × arctan((τ1/2 + τ2/2)/σ) = (1/2) × arctan((534.45 + 333.33)/σ)

Assuming a normal stress of 100 kPa, we get:

φ = (1/2) × arctan(867.78/100) = 21.16°

Substituting this value into the formula for the ratio of shear strength, we get:

τv/τh = tan(21.16°) + 1 = 1.41

Therefore, 1.41 the ratio of shear strength of the clay in vertical direction to that in horizontal direction.

Answer:

Draw up the contract for construction management.

Answer:

Work with construction management to solve specific problems as they arise.

Ensure compliance with safety standards.

Explanation:

As the particle content of a particle-reinforced composite is increased, the strength of the composite generally increases until a maximum strength is reached.

However, beyond this maximum point, the strength may begin to decrease due to increased particle-particle interactions leading to void formation and particle agglomeration.

Particle-reinforced composites are materials that consist of a matrix material (such as a polymer or metal) that is reinforced with small particles (such as ceramic or metal). The addition of particles to the matrix can improve the mechanical properties of the composite, such as strength and stiffness. However, there is a limit to the amount of particles that can be added before negative effects start to occur.

At low particle content, the particles act as stress concentrators and can cause microcracks in the matrix material, reducing the overall strength of the composite. As the particle content is increased, the particles start to bear more of the load and provide reinforcement to the matrix material, leading to an increase in strength. However, beyond a certain point, the increased particle-particle interactions can lead to the formation of voids and particle agglomeration, causing a decrease in strength. Therefore, the optimal particle content for a particular composite depends on the specific materials and intended application.

Answer:

The plotted diagram of line distance versus the transmission speed is uploaded below.

Explanation:

Given the data in the question;

Bit length B = 1000 bits

propagation velocity V = 2 × 10⁸ m/s

now, we know that the bit length of a link is expressed as;

B = R × d/V

where V is propagation velocity

d is the distance

R is the transmission speed

B is bit length

so we substitute

1000 = R × d/(2 × 10⁸)

1000 = Rd/(2 × 10⁸)

2 × 10¹¹ = Rd

R = 2 × 10¹¹ / d

R = 2E+11

Hence, we plot the transmission speed versus line distance; as shown in the image BELOW.

From the plot, if the transmission speed increases, the distances between stations decreases and vise versa.

Hence, both are inversely proportional.

The graph plot of line distance versus the transmission speed for a bit length of 1000 bits is; plotted below with Lν = 2 × 10¹¹ m/s

We are given;

Bit length; B = 1000 bits

Propagation velocity; V = 2 × 10⁸ m/s

Formula for bit length of a link is expressed as;

B = ν × L/V

where;

V is propagation velocity

L is the distance

ν is the transmission speed

B is bit length

Thus, plugging in the relevant values gives;

1000 = ν × L/(2 × 10⁸)

Thus;

Lν = 1000 × 2 × 10⁸

Lν = 2 × 10¹¹ m/s

Thus, find the attached image of a graph showing the line distance versus the transmission speed for a bit length of 1000 bits.

The length of the string is approximately 0.50 m.

To find the length of the string, we can use the formula T = 2π√(L/g), where T is the period of the oscillations, L is the length of the string, and g is the acceleration due to gravity.
First, we need to find the period of one oscillation. The student found that 10 oscillations take 12.0 s, so the period of one oscillation is 1.2 s (12.0 s ÷ 10).
Next, we can use the formula T = 2π√(L/g) and solve for L. Rearranging the formula, we get L = g(T/2π)^2.
We know that g is approximately 9.81 m/s^2 and T is 1.2 s, so plugging in those values we get:
L = 9.81 m/s^2 × (1.2 s/2π)^2
L ≈ 0.50 m

a. The maximum thickness of the copper nozzle is 3.3 mm

b. The maximum thickness of the steel nozzle is 0.054 mm

The question has to do with heat transfer

Heat transfer is the movement of heat energy from one body to anotrher.

Since the rate of heat loss by the gas equal rate of heat gain by the metal.

The rate of heat loss by gas is P = -hA(T - T') where

The rate of heat gain by metal is given by P' = kA(T - T")/t where

Since P = P', we have that

-hA(T - T') =  kA(T - T")/t

Making t subject of the formula, we have

t = -k(T - T")/h(T - T')

Given that for copper

Substituting the values of the variables into t, we have

t = -k(T - T")/h(T - T')

t = -378 W/m-K(540°C - 150°C)/[2 × 10⁴ W/m²-K(540°C - 2750°C)]

t = -378 W/m-K(390°C)/[2 × 10⁴ W/m²-K(-2210°C)]

t = 147420 W/m/4420 × 10⁴ W/m²

t = 147420 W/m/44200000 W/m²

t = 0.0033 m

t = 3.3 mm

So, the maximum thickness of the copper nozzle is 10.71 cm

Given that for steel

Substituting the values of the variables into t, we have

t = -k(T - T")/h(T - T')

t = -23.2 W/m-K(980°C - 150°C)/[2 × 10⁴ W/m²-K(980°C - 2750°C)]

t = -23.2 W/m-K(830°C)/[2 × 10⁴ W/m²-K(-1770°C)]

t = 19256 W/m/3540 × 10⁴ W/m²

t = 19256 W/m/35400000 W/m²

t = 0.0000544 m

t = 0.0544 mm

t ≅ 0.054 mm

A runway identified as runway 27 serves operations oriented to the westward direction.

What are runways?

A runway is defined as an airport's paved surface. A runway is used for aircraft takeoff and landing operations. The most important runway, without a doubt, is the primary runway, which is the longest runway that has lighting and instrument landing aids. Runways are usually numbered based on their compass bearings, and they are designated L or R if two runways are close together but not parallel. It's worth noting that the numbers don't signify the degree to which the runway is off of a north-south heading, but rather the runway's magnetic bearing.  

How to identify the approximate direction of operations from the runway designation?

A runway identified as runway 27 serves operations oriented to the westward direction. The runway numbering system is used to determine the runway direction, which is based on its magnetic direction from 0 to 359 degrees. These numbers are used to designate runway headings in tens, as well as for headings within ten degrees. Runway 27 would be the one with the magnetic heading of approximately 270 degrees (270-279). As a result, an aircraft taking off or landing on runway 27 would travel in an approximately westward direction.

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

With each modification, the software becomes increasingly disorganized. System maintenance hampered by these problems, as it is harder identifying the source of bugs in poorly designed systems. Also, keeping the documentation up to date over successive "evolution" is uncommon. Poor documentation also makes maintenance more difficult.

・It leads to implementing and then repairing way of building systems.

・Practically, this methodology may increase the complexity of the system as scope of the system may expand beyond original plans.

・Incomplete application may cause application not to be used as the full system was designed.
