The structural number of the pavement, constructed with 5 inches of the sand-mix asphaltic wearing surface is 14.5.

The structural number is an estimate of the number of inches of asphaltic wearing surface that a pavement can support without exceeding the allowable structural layer strain. It is calculated by multiplying each layer's drainage coefficient by its thickness and then adding the products together.

T In this case, the 5-inch wearing surface has a drainage coefficient of 0.90, the 9-inch base has a coefficient of 1.0, and the 10-inch subbase has a coefficient of 1.0.

The structural number can be calculated by using the following formula:

SN = (5 x 0.90) + (9 x 1.0) + (10 x 1.0) = 14.5. Therefore, the structural number of the pavement is 14.5.

The shear plane angle is calculated as 49.4 degrees while the shear strain is given as 1.17

Shear strain is a measure of deformation resulting from an applied force that is parallel to the surface of an object. It is usually expressed as a fractional change in the length of the object. Shear strain is a measure of the displacement of the surface points of an object in the direction perpendicular to the direction of the applied force.

The shear plane angle is the angle between the plane of shear stress and the normal to the plane of shear. It is typically measured in degrees and can range from 0 to 90 degrees.

(a) Shear plane angle = tan⁻¹((0.65-0.30)/0.30) = 49.4°

(b) Shear strain = (deformed chip thickness - initial chip thickness)/initial chip thickness

Substituting the values into the formula;

Answer:

a)  Cr = Co - Fx / D

b)   ΔC / Δx = ( CR - Cr )  / ( xR - xRo )

Explanation:

A) Derive an expression for the profile c(r) inside the tissue

F = DΔC / X  = D ( Co - Cr ) / X   ------ 1

where : F = flux , D = drug diffusion coefficient

            X = radial distance between Ro and R

Hence : Cr = Co - Fx / D

B) Express the diffusive flux at outer surface of the balloon

Diffusive flux at outer surface =  ΔC / Δx = CR - Cr / xR - xRo

The function that causes values of both x and to develop the highest feasible moment at A according to the provided suspended mass is written as 14715 Nm (clockwise).

The quantity of matter or substance that makes up a thing is known as its mass. The unit of measurement is the kilogramme, abbreviated as kg. It's crucial to keep in mind that mass differs from weight. While weight varies with changes in gravity, mass never changes.

We have identified the following values,

adjust for any angle 00 ≤ θ ≤ 900 any extension 0 ≤ x ≤ 5 m.

So,

Let us consider an equation to calculate the moment using θ and x as variables around point A.

⇒ ((9−1.5) + x) (cosθ) (120) (9.81)

When we are simplifying the given equation gives us:

⇒ MA ​= (7.5+x) 1177.2 cosθ

Here the maximum moment will develop if θ = 0 and x=5 m.

Then, by substituting these values gives us:

⇒ MA​=(7.5+x)1177.2cosθ

⇒ MA​=(7.5+5)1177.2cos00

Thus, the value of MA is written as, 14715 Nm (clockwise)

The principal of the loan that TMI Systems repaid was $90,000.

The formula to calculate the principal of a loan is P = L + I, where P is the principal, L is the loan amount, and I is the total interest paid over the duration of the loan.

In this case, we are given that the loan amount was 10% per year simple interest, which can be calculated by multiplying the principal by the interest rate (0.1) and the duration of the loan (5 years). Therefore, the total interest paid over the duration of the loan is P x 0.1 x 5 = $50,000.

We are also given the total amount repaid, which is the sum of the principal and the total interest paid. Therefore, we can calculate the principal by subtracting the total interest paid from the total amount repaid.

This gives us $140,000 - $50,000 = $90,000. As the principal must be a positive value, the principal of the loan is $90,000.

To solve this, let's build some relationships among the power, voltage, current and number of loops in an ideal transformer.

For an ideal transformer, the powers generated by the primary and secondary coils are the same. In other words, the input power and output power remain the same.

Input power = Output power

Where;

Input power = [tex]V_{p}[/tex] x [tex]I_p[/tex]

Output power = [tex]V_{s}[/tex] x [tex]I_s[/tex]

=> [tex]V_{p}[/tex] x [tex]I_p[/tex] = [tex]V_{s}[/tex] x [tex]I_s[/tex]

This can be re-written as:

[tex]\frac{V_p}{V_s}[/tex] = [tex]\frac{I_s}{I_p}[/tex]             ------------------(i)

Also, the transformer turns ratio (r) is the quotient of the number of turns/loops in the primary coil and the number of turns/loops in the secondary coil. i.e

r = [tex]\frac{N_p}{N_s}[/tex]

This ratio is equal to the ratio given in equation (i) i.e

r = [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex] = [tex]\frac{I_s}{I_p}[/tex]

=> r = [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex]

=> [tex]\frac{N_p}{N_s}[/tex] = [tex]\frac{V_p}{V_s}[/tex]

This can be re-written as

=> [tex]\frac{N_s}{N_p}[/tex] = [tex]\frac{V_s}{V_p}[/tex]       -----------(ii)

From the question,

[tex]V_{p}[/tex] = 120V

[tex]V_{s}[/tex] = 100kV = 100000V

Substitute these values into equation (ii) as follows;

[tex]\frac{N_s}{N_p}[/tex] = [tex]\frac{100000}{120}[/tex]

[tex]\frac{N_s}{N_p}[/tex] =  [tex]\frac{10000}{12}[/tex]

[tex]\frac{N_s}{N_p}[/tex] =  [tex]\frac{2500}{3}[/tex]

Therefore, the ratio of the number of loops in the secondary to the number of loops in the primary is 2500 : 3

Using the formula of shear stress, the minimum required diameter is 0.81mm

Shear stress is a force that causes two objects to slide past each other in opposite directions. It is the force per unit area of the surface on which the force is applied. Shear stress is often caused by two objects rubbing against each other, such as a car tire sliding on the road. It can also be caused by wind, gravity, or other forces.

The shear stress on the shaft can be calculated using the formula:

τ(allow) = P/(2*π*d*J)

where P is the total power transferred by the shaft, d is the diameter of the shaft, and J is the polar moment of inertia.

J = π*d⁴/32

Substituting the given values,

τ(allow) = (15 + 6 + 4 + 5)/(2*π*d*π*d⁴/32)

d = √[32*(15 + 6 + 4 + 5)/(τ(allow)*2*π²)]

d = √[32*(30)/(75*2*π²)]

d = 0.81mm

The number of elements determines the length of the sequence (possibly infinite). In contrast to a set, the same elements can appear multiple times in a sequence at different positions, and unlike a set, the order matters.
