If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

The magnitude of the electric field due to a point source charge decreases as the distance from the source charge increases.

As the distance from a point source charge increases, the magnitude of the electric field it produces decreases. This is a result of the inverse-square law, which states that the intensity of the electric field diminishes as the square of the distance from the source. As the distance increases, the electric field spreads out over a larger area, resulting in a decrease in its strength. This behavior is consistent with the concept that electric field lines emanate radially outward from a point charge and become less concentrated as they move farther away.

In summary, the magnitude of the electric field due to a point source charge diminishes as the distance from the charge increases, following the inverse-square law.

Answer:

Beam of 25" depth and 12" width is sufficient.

I've attached a detailed section of the beam.

Explanation:

We are given;

Beam Span; L = 20 ft

Dead load; DL = 0.50 k/ft

Live load; LL = 0.65 k/ft.

Beam width; b = 12 inches

From ACI code, ultimate load is given as;

W_u = 1.2DL + 1.6LL

Thus;

W_u = 1.2(0.5) + 1.6(0.65)

W_u = 1.64 k/ft

Now, ultimate moment is given by the formula;

M_u = (W_u × L²)/8

M_u = (1.64 × 20²)/8

M_u = 82 k-ft

Since span is 20 ft, it's a bit larger than the average span beams, thus, let's try a depth of d = 25 inches.

Effective depth of a beam is given by the formula;

d_eff = d - clear cover - stirrup diameter - ½Main bar diameter

Now, let's adopt the following;

Clear cover = 1.5"

Stirrup diameter = 0.5"

Main bar diameter = 1"

Thus;

d_eff = 25" - 1.5" - 0.5" - ½(1")

d_eff = 22.5"

Now, let's find steel ratio(ρ) ;

ρ = Total A_s/(b × d_eff)

Now, A_s = ½ × area of main diameter bar

Thus, A_s = ½ × π × 1² = 0.785 in²

Let's use Nominal number of 3 bars as our main diameter bars.

Thus, total A_s = 3 × 0.785

Total A_s = 2.355 in²

Hence;

ρ = 2.355/(22.5 × 12)

ρ = 0.008722

Design moment Capacity is given;

M_n = Φ * ρ * Fy * b * d²[1 – (0.59ρfy/fc’)]/12

Φ is 0.9

f’c = 4,000 psi = 4 kpsi

fy = 60,000 psi = 60 kpsi

M_n = 0.9 × 0.008722 × 60 × 12 × 22.5²[1 - (0.59 × 0.008722 × 60/4)]/12

M_n = 220.03 k-ft

Thus: M_n > M_u

Thus, the beam of 25" depth and 12" width is sufficient.

The non-linearity error as a percentage of the full-scale reading at 100 degree C  is - 0.89%.

Non-linearity error is defined as the biggest deviation from a straight line linking the output signal to the applied force, known as the "best straight," that the calibration curve makes. In order to eliminate second order nonlinearity, the sensor signal conditioning system feeds a portion of the output signal back to the sensor.

If EMF and Celsius temperature have a proportional relationship, then the recorded value of EMF at 100 °C will be understood to be a temperature of.

T/5.268 = 400/21.846

T = 5.268(400/21.846) ≈ 96.457 °C

As a percentage of the full scale, the mistake is

(96.457 -100)/400 × 100% ≈ -0.886%

Explanation:

A composite material is made up of two material which have different properties (chemically or physically). The two materials are mixed in such a way that it improves the properties of both the materials (the one  in the matrix and the other in the filler) thereby enhancing the overall strength and stiffness of the matrix.

Hence, option D is correct

A correct option is an option (c)

The main advantage of the composite is there higher strength as compared to the matrix.

The strength is very low as compared to the resultant composite and the fiber.

The resultant strength can be calculated in two direction

The longitudinal way is,

\(E=V_mE_m+V_fE_f...(1)\)

The transversal way is,

\(\frac{1}{E}=\frac{V_m}{E_m}+\frac{V_f}{E_f} ...(2)\)

no. of turns in the primary coil, \(N_i=230\)

\(V_o=5.60~V\)

\(\frac{N_i}{N_o} =\frac{V_i}{V_o}\)

\(\frac{N_o}{230}=\frac{5.60}{220}\)

\(N_o=5.85\approx 6\) turns compensating the losses

\(V_o=12.0~V\)

\(\frac{N_i}{N_o} =\frac{V_i}{V_o}\)

Energy attenuation system is designed to control the kinetic energy of an object during an impact or collision to reduce the damage caused by the impact. When designing an energy attenuation system for a 1200 kg car traveling at 100 km/hr at impact, there are various factors that need to be considered.

The first factor is the speed of the car, which is 100 km/hr. The energy of the car can be calculated using the formula E = 0.5mv^2, where E is the kinetic energy, m is the mass of the car, and v is the velocity of the car. Therefore, the kinetic energy of the car can be calculated as follows: E = 0.5 x 1200 kg x (100 km/hr)^2= 3,333,333.33 JoulesTo control the energy of the car at impact, the energy attenuation system needs to absorb this energy gradually.

The faster the car is traveling, the higher the kinetic energy, and therefore, the more difficult it is to design a system that can control the energy of the car at impact. A car traveling at a fast speed requires a more advanced energy attenuation system, which can absorb the energy of the car gradually and reduce the force of the impact to safe levels.

In conclusion, designing an energy attenuation system for a car traveling at a fast speed requires a more advanced system than one for a car traveling at a slower speed. The system needs to be designed in such a way that it can absorb the energy of the car gradually, and the force of the impact is reduced to safe levels. The design of the system should ensure that the passengers are safe and are not exposed to any serious injuries.

The values of h at the two internal boundaries are :

Given data :

Z₁ = Z₂ = Z₃ = 25 m

h top = 120 m

h bottom = 100 m

K₁ = 0.0001 m/s

K₂ = 0.0005 m/s

K₃ = 0.0010 m/s

we will apply the formula below since flow is perpendicular to the bedding plane

Keq = \(\frac{Z1 + Z2 + Z3 }{\frac{Z1}{K1}+\frac{Z2}{K2} + \frac{Z3}{K3} }\)  ----- ( 1 )

Insert values given above into equation 1

Therefore ; Keq = 2.307 * 10⁻⁴ m/s

Hydraulic gradient ( Ieq ) = head loss / length

                                          = ( 120 - 100 ) / 3 * 25

                                   Ieq  = 0.266

Given that the flow is perpendicular to bedding plane

q1 = q2 = q3

V₁ = V₂ = V₃ = V

K₁i₁ = K₂i₂ = K₃i₃ = Keq * ieq

Hence :

V = Keq* Ieq

   = 2.307 * 10⁻⁴ * 0.266

   = 6.15 * 10⁻⁵ m/s .

Also;

K₁i₁ =  Keq * ieq = K₂i₂ = K₃i₃

therefore :

a) The ductility = -30.12%

the negative sign means reduction

Therefore, there is 30.12% reduction

b) the true stress at fracture is 658.26 Mpa

Explanation:

Given that;

Original diameter \(d_{o}\) = 12.8 mm

Final diameter \(d_{f}\) = 10.7

Engineering stress  \(\alpha _{E}\) = 460 Mpa

a) determine The ductility in terms of percent reduction in area;

Ai = π/4(\(d_{o}\) )²  ; Ag = π/4(\(d_{f}\) )²

% = π/4 [ ( (\(d_{f}\) )² - (\(d_{o}\) )²) / ( π/4  (\(d_{o}\) )²) ]

= ( (\(d_{f}\) )² - (\(d_{o}\) )²) / (\(d_{o}\) )² × 100

we substitute

= [( (10.7)² - (12.8)²) / (12.8)² ] × 100

= [(114.49 - 163.84) / 163.84 ] × 100

= - 0.3012 × 100

= -30.12%

the negative sign means reduction

Therefore, there is 30.12% reduction

b) The true stress at fracture;

True stress  \(\alpha _{T}\) = \(\alpha _{E}\) ( 1 +  \(E_{E}\) )

\(E_{E}\)  is engineering strain

\(E_{E}\)  = dL / Lo

= (do² - df²) / df² = (12.8² - 10.7²) / 10.7² = (163.84 - 114.49) / 114.49

= 49.35 / 114.49  

\(E_{E}\) = 0.431

so we substitute the value of \(E_{E}\)  into our initial equation;

True stress  \(\alpha _{T}\) = 460 ( 1 +  0.431)

True stress  \(\alpha _{T}\) = 460 (1.431)

True stress  \(\alpha _{T}\) = 658.26 Mpa

Therefore, the true stress at fracture is 658.26 Mpa
