The ratio of maximum shear stresses in the hollow and solid bars is (15/16).To calculate the ratio of torsional stiffnesses between a hollow and solid bar, and the ratio of their maximum shear stresses, we can use the concept of polar moment of inertia (J) and the torsion formula.

Ratio of Torsional Stiffnesses: The torsional stiffness of a bar is proportional to its polar moment of inertia. For a solid bar, the polar moment of inertia is given by J_solid = (π/32) * (d^4), where d is the diameter of the solid bar.

For a hollow bar with an inner diameter of d/2, the polar moment of inertia is given by J_hollow = (π/32) * (d^4 - (d/2)^4).

The ratio of torsional stiffnesses (K) between the hollow and solid bars is then: K = J_hollow / J_solid = [(d^4 - (d/2)^4)] / d^4 = (15/16)

Ratio of Maximum Shear Stresses: The maximum shear stress (τ_max) in a bar under torsion is given by the formula τ_max = (T * r) / J, where T is the applied torque and r is the radial distance from the center of the bar.

Since both the hollow and solid bars are subjected to the same torque, the ratio of their maximum shear stresses will be the same as the ratio of their polar moments of inertia:

τ_max_hollow / τ_max_solid = J_hollow / J_solid = (15/16)

Therefore, the ratio of maximum shear stresses in the hollow and solid bars is (15/16).

Concatenating two transmission lines with different impedances can result in reflections and signal degradation. To avoid this, a matching circuit can be used to transform the impedance of one line to match the other.

One common way to match two transmission lines with impedances Z1 and Z2 is to use a T-network matching circuit, consisting of a 10 Ohm, 45 Ohm, and 60 Ohm resistor. The exact values of the resistors will depend on the specific impedances of the transmission lines. To demonstrate that the transmission lines are matched from both directions, the T-network should be tested in both directions. If the reflection coefficient is close to zero in both directions, it indicates that the matching circuit has effectively transformed the impedances to be matched. It is important to note that the design of a matching circuit is a complex process and the specific values of the resistors will depend on the specific impedance values and frequencies of the transmission lines.

Answer:

E = 8.83 kips

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

Now, the modulus of elasticity (E) is given as:

The voltage across each light in the series circuit is approximately 2.5 volts.

To determine the voltage across each light in a series circuit, you need to know the total resistance of the circuit and the total voltage applied. In this case, the total resistance of the circuit can be calculated by adding up the resistances of each individual light.

Since there are forty-eight lights connected in series, and each light has a resistance of 1,000 ohms, the total resistance of the circuit would be:

Total resistance = 48 lights * 1,000 ohms/light = 48,000 ohms

Given that the total voltage applied to the circuit is 120 volts, we can use Ohm's Law to determine the voltage across each light. Ohm's Law states that the voltage (V) is equal to the current (I) multiplied by the resistance (R):

V = I * R

In a series circuit, the current is the same throughout. Therefore, we can use Ohm's Law to find the current flowing through the circuit:

I = V / R_total

I = 120 V / 48,000 ohms

I ≈ 0.0025 A (or 2.5 mA)

Hot combustion gases, modeled as air behaving as an ideal gas, enter a steady-state turbine at 145 psi, 2700oR, and exit at 29 psi and 1974oR. The power output is 74.26 hp, and heat transfer from the turbine to the surroundings occurs at a rate of 14 BTU/s.

Required:

a)Determine the power output of the turbine, in hp.

b) The Flow rate

Answer:

a) \(w=74.26hp\)

b) \(m=0.22\)

Explanation:

From the question we are told that:

Initial Pressure \(p_1= 145 psi\)

Initial Temperature \(T_1 =2700oR=>2240.33^oF\)

Final Pressure \(p_2= 29 psi\)

Final Temperature \(t_2=1974oR=>1514.33^oF\)

Output Power \(w=74.26hp\)

Heat transfer Rate \(Q=14BTU/s\)

Generally the equation for Steady flow energy is mathematically given by

 \(Q-w=m(h_2-h_1)\)

Where

 \(m=Flow\ rate\)

From Steam table

 \(h_1=704btu/ib (at\ p_1= 145\ psi,\ T_1 =2700oR=>2240.33^oF )\)

 \(h_2=401btu/ib (at\ p_2= 29psi\ t_2=1974oR=>1514.33^oF )\)

Therefore

 \(-14-74.26=m(401-704)\)

 \(m=\frac{-14-74.26}{(401-704)}\)

 \(m=0.22\)
