Answer:

a) The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

b) The change in diameter of the specimen is  - 0.015 mm

Explanation:

Given the data  in the question;

(a) The amount by which this specimen will elongate in the direction of the applied stress.

First we find the area of the cross section of the specimen

A = \(\frac{\pi }{4}\) d²

our given diameter is 20.5 mm so we substitute

A = \(\frac{\pi }{4}\) ( 20.5 mm )²

A = 330.06 mm²

Next, we find the change in length of the specimen using young's modulus formula

E = σ/∈

E = P/A × L/ΔL

ΔL = PL/AE

P is force ( 46300 N), L is length ( 201 mm ), A is area ( 330.06 mm² ) and E is  elastic modulus (60.5 GPa) = 60.5 × 10⁹ N/m² = 60500 N/mm²

so we substitute

ΔL = (46300 N × 201 mm) / ( 330.06 mm² × 60500 N/mm² )

ΔL =  0.466 mm

Therefore, The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

Using the following relation for Poisson ratio

μ = -  Δd/d / ΔL/L

given that Poisson's ratio of the metal is 0.33

so we substitute

0.33 = -  Δd/20.5 / 0.466/201

0.33 = -  Δd201 / 20.5 × 0.466

0.33 = - Δd201  / 9.143

0.33 × 9.143 =  - Δd201

3.01719 = -Δd201

Δd = 3.01719 / - 201

Δd  = - 0.015 mm

Therefore, The change in diameter of the specimen is  - 0.015 mm

The frequency  is 6.67 kHz and the duty cycle is:16.67%.

​Given:

Pulse width=25

Period=150

Frequency:

Frequency=1/(150×10^-6)

Frequency=1/0.00015

Frequency=6.666 kHz

Frequency=6.67 kHz (Approximately)

Duty cycle:

Duty cycle=(25×10^-6)/ (150×10^-6)×100%

Duty cycle=16.67%

Therefore the frequency  is 6.67 kHz and the duty cycle is:16.67%.

The amount of open-loop phase change required to cause an unstable closed-loop system is known as the phase margin.

Phase crossover occurs at 0.010 Hz, hence the gain margin is 1.00/0.45=2.22 at that frequency. The amount of degrees that the phase angle at the gain crossover is less than 180° is known as the phase margin.

When an input change, like as a step function, is applied, phase margin reflects relative stability, or the propensity to oscillate during that response. Gain margin shows utmost stability and how much the system will swing unrestrainedly in the presence of any disruption.

When G(jw)|=1, the phase of G(jw) is greater than -180deg, which is referred to as a positive phase margin. The system's level of stability can be determined in this way. In terms of stability, a wider phase margin is preferable. System instability is indicated by a negative phase margin.

The market for textbooks has a shortage. There will be an upward pressure on price, which will cause quantity demanded to fall and quantity supplied to rise.

Explanation:

The complete question is attached to this solution.

Note that

- The quantity demanded is the negative sloping line in colour blue indicating that the quantity demanded increases as the price of the commodity (textbook) falls and the quantity demanded rises as the price of the textbook falls.

- The quantity supplied is the positive sloping line in colour red/orange indicating that the quantity supplied decreases as the price of the commodity (textbook) falls and the quantity supplied increases as the price of the textbook falls.

The quantity demanded and the quantity supplied balance each other and cross path at a point called the equilibrium point.

The price at this point is called the equilibrium price and the quantity at this point is the equilibrium quantity.

For this question, the equilibrium price = $150 and the equilibrium quantity that matches quantity demanded with quantity supplied = 500.

At prices greater than the equilibrium price, the quantity demanded falls and the quantity supplied increases, hence, there is a surplus of the commodity (textbook) as the quantity of textbooks supplied is way more than the quantity demanded and there is more than required textbooks.

At prices lower than the equilibrium price, the quantity demanded increases and the quantity supplied reduces, hence, there is a shortage of commodity (textbook) as all of the goods supplied are totally bought with extra demand remaining.

When there is a surplus or shortage, the market forces that are responsible for price fixing and quantity demanded work together to take the market back to equilibrium.

So, when the price is higher than equilibrium price and there is a surplus, the market works to reduce the price of the commodity so that quantity demanded can rise and quantity supplied can fall to counter this surplus.

When the price is lower than equilibrium price and there is a shortage, the market works to increase the price of the commodity so that quantity demanded can fall and quantity supplied can rise to counter this shortage.

The price of the textbook in the question, $125, is lower than the equilibrium price, $150, hence, there will be a shortage of textbooks because the quantity demanded, at this price, is higher than the quantity that will be supplied.

So, there is then a pressure on the price to rise back so that the quantity demanded reduces and the quantity supplied increases.

Answer: the surface shear stress at x =1m from the leading edge of the plate is 4.1973 N/m²

Explanation:

Given that;

density s = 1.16 kg/m³

velocity = u = 50 m/s

kinetic viscosity r = 15.89 × 10⁻⁶ m²/s

xL = 1m from the leading edge of the plate

Now Reynold number (Rex)

Rex = UxL / r

Rex = (50 m/s × 1m ) / 15.89 × 10⁻⁶ m²/s

Rex = 3146633.1025

since Rex is greater than 5×10⁵ { Turbulent flow }

so Local skin friction coefficient

⇒ Cfx = 0.0577 / (Rex)^1/5

Cfx = 0.0577 / (3146633.1025)^1/5

Cfx = 0.0028947

Now Shear stress (y)

y = Cfx × 1/2 × su²

y = 0.0028947 × 1/2 × 1.16 × (50)²

y = 4.1973 N/m²

∴ the surface shear stress at x =1m from the leading edge of the plate is 4.1973 N/m²

The peak runoff rate from the shopping center during a 50-year storm is approximately 0.296 m/s.

To calculate the peak runoff rate from the shopping center during a 50-year storm, use the Rational Method, which is given as

Q = (C * I * A) / 3600

where

Q is the peak runoff rate in m/s,

C is the runoff coefficient,

I is the rainfall intensity in mm/h, and

A is the total area of the shopping center in \(m^2.\)

Assuming a 50-year storm has a rainfall intensity of 152 mm/h based on the IDF curve example.

Using the runoff coefficients for the different surfaces in the shopping center, we can calculate the total area-weighted runoff coefficient as follows

C = [(0.95 * 71,000) + (0.85 * 17,000) + (0.65 * 22,000) + (0.90 * 5,000) + (0.70 * 25,000)] / (71,000 + 17,000 + 22,000 + 5,000 + 25,000)

C = 0.807

The total area of the shopping center is

A = 71,000 + 17,000 + 22,000 + 5,000 + 25,000 = 140,000 \(m^2\)

Now we can calculate the peak runoff rate

Q = (C * I * A) / 3600

Q = (0.807 * 152 * 140,000) / 3600

Q = 41.5 \(m^3/s\) or 41.5 / 140 = 0.296 m/s

Therefore, the peak runoff rate from the shopping center during a 50-year storm is approximately 0.296 m/s.

Given:-

- Temperature of hot fluid at inlet:  \(T_h_i = 300\) °C

- Temperature of cold fluid at outlet: \(T_c_o = 120\) °C

- Temperature of cold fluid at inlet: \(T_c_i = 35\) °C

- The overall heat transfer coefficient: U = 1500 W / m^2 K

- The flow rate of cold fluid: m_c = 10,00 kg/ h

- The flow rate of hot fluid: m_h = 5,000 kg/h

Solution:-

- We will evaluate water properties at median temperatures of each fluid using table A-4.

Cold fluid:   Tci = 35°C , Tco = 35°C

                            Tcm = 77.5 °C ≈ 350 K  --- > \(C_p_c = 4195 \frac{J}{kg.K}\)

 Hot fluid:     Thi = 300°C , Tho = 150°C ( assumed )

                             Thm = 225 °C ≈ 500 K --- > \(C_p_h = 4660 \frac{J}{kg.K}\)

- We will use logarithmic - mean temperature rate equation as follows:

                             \(A_s = \frac{q}{U*dT_l_m}\)

Where,

                 A_s : The surface area of heat exchange

                 ΔT_lm: the logarithmic differential mean temperature

                 q: The rate of heat transfer

- Apply the energy balance on cold fluid as follows:

                   \(q = m_c * C_p_c * ( T_c_o - T_c_i )\\\\q = \frac{10,000}{3600} * 4195 * ( 120 - 35 )\\\\q = 9.905*10^5 W\)

- Similarly, apply the heat balance on hot fluid and evaluate the outlet temperature ( Tho ) :

                   \(T_h_o = T_h_i - \frac{q}{m_h * C_p_h} \\\\T_h_o = 300 - \frac{9.905*10^5}{\frac{5000}{3600} * 4660} \\\\T_h_o = 147 C\)

- We will use the experimental results of counter flow ( unmixed - unmixed ) plotted as figure ( Fig . 11.11 ) of the " The fundamentals to heat transfer" and determine the value of ( P , R , F ).

- So the relations from the figure 11.11 are:

                  \(P = \frac{T_c_o - T_c_i}{T_h_i - T_c_i} \\\\P = \frac{120 - 35}{300 - 35} \\\\P = 0.32\)    

                 \(R = \frac{T_h_i - T_h_o}{T_c_o - T_c_i} \\\\R = \frac{300 - 147}{120 - 35} \\\\R = 1.8\)

Therefore,         P = 0.32 , R = 1.8 ---- > F ≈ 0.97

- The log-mean temperature ( ΔT_lm - cf ) for counter-flow heat exchange can be determined from the relation:

                        \(dT_l_m = \frac{( T_h_i - T_c_o ) - ( T_h_o - T_c_i ) }{Ln ( \frac{( T_h_i - T_c_o )}{( T_h_o - T_c_i )} ) } \\\\dT_l_m = \frac{( 300 - 120 ) - ( 147 - 35 ) }{Ln ( \frac{( 300-120 )}{( 147-35)} ) } \\\\dT_l_m = 143.3 K\)

- The log - mean differential temperature for counter flow is multiplied by the factor of ( F ) to get the standardized value of log - mean differential temperature:

                       \(dT_l = F*dT_l_m = 0.97*143.3 = 139 K\)

- The required heat exchange area ( A_s ) can now be calculated:

                     \(A_s = \frac{9.905*10^5 }{1500*139} \\\\A_s = 4.75 m^2\)

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.
