Explanation:
A rope is wrapped three and a half times around a cylinder. Determine the range of force T exerted on
the free end of the rope for maintaining equilibrium that is required to just support a 5 kN weight. The
coefficient of friction between the rope and the cylinder is 0.2
The range of force exerted at the end of the rope is; 285.7 N to 1,000 N.
What is the Net horizontal force?The net horizontal force of the cylinder when it is at equilibrium position can be found by applying Newton's second law of motion. Thus;
∑F = 0
F - μF_n = 0
We are given;
F_n = 5 kN = 5000 N
μ = 0.2
Thus;
F - 0.2(5,000) = 0
F - 1,000 = 0
F = 1,000 N
The strength of the applied force will be increasing as the number of turns of the rope increases. Thus;
Minimum force = Total force/number of turns of rope
Since rope is wrapped three and half times, then;
number of turns = 3.5
Thus;
minimum force = 1,000/3.5
minimum force = 285.7 N
Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

Consider a convergent duct with an inlet area A1 = 5 m2. Air enters this duct with a velocity V1=10m/s and leaves the duct exit with a velocity V2=30 m/s.
Required:
a. What is the area of the duct exit?
b. If the air pressure and temperature at the inlet area are 1.2 x105 N/m2, and 300K, respectively, what is the pressure at the exit?
Answer:
(a) The area of the duct exit is 1.67 m²
(b) The air pressure at the exit is 1.195 x 10⁵ N/m²
Explanation:
Given;
inlet area, A₁ = 5 m²
inlet velocity, V₁ = 10 m/s
exit velocity, V₂ = 30 m/s
(a) The area of the duct exit is determined by applying continuity equation;
A₁V₁ = A₂V₂
Where;
A₂ is the area of the duct exit
A₂ = (A₁V₁) / (V₂)
A₂ = (5 x 10) / (30)
A₂ = 1.67 m²
(b) Apply Bernoulli’s equation to determine the pressure at the exit;
[tex]P_1 + \frac{\rho V_1^2}{2} = P_2 + \frac{\rho V_2^2}{2}\\\\P_2 = P_1 + \frac{\rho V_1^2}{2} - \frac{\rho V_2^2}{2}\\\\P_2 = P_1 + \frac{\rho }{2} (V_1^2 - V_2^2)[/tex]
Density of air at 300k = 1.177 kg/m³
[tex]P_2 = P_1 + \frac{\rho }{2} (V_1^2 - V_2^2)\\\\P_2 = 1.2*10^5 \ + \ \frac{1.177}{2} (10^2 - 30^2)\\\\P_2 = 1.2*10^5 \ + \ -470.8\\\\P_2 = 1.195*10^5 \ N/m^2[/tex]
Therefore, the air pressure at the exit is 1.195 x 10⁵ N/m²
From the top of a vertical cliff 80m high, the angles of depression of 2 buoys lying due west of the cliff are 23° and 15° respectively. How far are the buoys apart?
Answer:
110 m
Explanation:
The geometry of the problem can be modeled by a right triangle. The height of the cliff forms one leg, and the distance to a buoy forms the other leg. The angle of depression is opposite the height of the cliff. An appropriate trig relation is ...
Tan = Opposite/Adjacent
Solving for the Adjacent side (the distance to the buoy), we find ...
Adjacent = Opposite/Tan
distance to buoy 1 = (80 m)/tan(23°) ≈ 188.468 m
distance to buoy 2 = (80 m)/tan(15°) ≈ 298.564 m
Then the distance between the buoys is ...
298.564 -188.468 m ≈ 110 m
The buoys are about 110 meters apart.

Technician A says that a circuit with continuity reads 0 ohms. Technician B says that an open circuit reads 0 ohms. Who is correct
Answer:
A
Explanation:
An open circuit has infinite resistance, not 0. A circuit with continuity usually measures a few ohms or less, depending on the length and gauge of the wire and the condition of the connections. Often, on a general-purpose ohmmeter, the reading is very near 0 ohms.
Technician A is correct.
Calculate the current in the coiled heating element of a 240-V stove. The resistance of the element is 60 ohms at its operating temperature.
Answer:
4 A
Explanation:
Current is found using Ohm's law.
I = V/R
I = (240 volts)/(60 ohms) = 4 A
The heating element current is 4 amperes.

The Stefan-Boltzmann law can be employed to estimate the rate of radiation of energy H from a surface, as in
H = Aeσ^4
where H is in watts, A = the surface area (m^2 ), e = the emissivity that characterizes the emitting properties of the surface (dimensionless), σ = a universal constant called the Stefan-Boltzmann constant (= 5.67 x 10^8 W m^2 K^-4 ), and T = absolute temperature (K).
Required:
Determine the error of H for a steel plate with A = 0.15 m^2 , e = 0.90, and T 5 650 ± 20.
b. Compare your results with the exact error. Repeat the computation but with T = 650 ± 40. Interpret your results.
Explanation:
A.
H = Aeσ^4
Using the stefan Boltzmann law
When we differentiate
dH/dT = 4AeσT³
dH/dT = 4(0.15)(0.9)(5.67)(10^-8)(650)³
= 8.4085
Exact error = 8.4085x20
= 168.17
H(650) = 0.15(0.9)(5.67)(10^-8)(650)⁴
= 1366.376watts
B.
Verifying values
H(T+ΔT) = 0.15(0.9)(5.67)(10)^-8(670)⁴
= 1542.468
H(T+ΔT) = 0.15(0.9)(5.67)(10^-8)(630)⁴
= 1205.8104
Error = 1542.468-1205.8104/2
= 168.329
ΔT = 40
H(T+ΔT) = 0.15(0.9)(5.67)(10)^-8(690)⁴
= 1735.05
H(T-ΔT) = 0.15(0.9)(5.67)(10^-8)(610)⁴
= 1735.05-1059.83/2
= 675.22/2

This car is parked. The engine is off and there is no music playing, What energy is currently in use?
Answer:
Potential energy
Explanation:
"Potential energy" is a type of energy an object has when it's at rest or in this case not moving. The car is parked, and the engine is off, that means there is no electrical, kinetic, thermal, or mechanical energy in play since the engine isn't running and the car isn't moving. The radio is off too so that means there is no sound energy or electric energy (again) in play either. You are just parked with the car completely shut off, but you do have the potential to move the car by turning on the engine and start driving, which means potential energy is currently in use.

(TCO 6) A cable company is running a fiber-optic link between the head end and a neighborhood five miles away. The signal applied to the fiber goes through an optical connector having 3dB LOSS at the head end, the fiber has a LOSS of 1 dB, and the connector at the end of the fiber has a LOSS of 3 dB before being applied to an amplifier used to make up for the losses. The desired signal at the output of the amplifier is 10 dBm, and the signal level applied to the fiber connector at the head end is 10 dBm. What should the gain of the amplifier be to have 10 dBm at the output of the neighborhood amplifier
Answer:
7 dB
Explanation:
The total loss from the headend to the amplifier input is the sum of the losses along the fiber, that we simply add as they are in dBs:Total Loss = 3 dB + 1 dB + 3 dB = 7 dBThe signal at the amplifier input is just +10 dBm- 7 dB = +3 dBmSo as the output level at the Headend and the one at the output of the neighborhood amplifier must be equal each other (compensating all losses in the path), the amplifier gain must be equal to the cumulative loss, i.e. , 7 dB, so that the amplifier output level be + 10 dBm.3.
