What is Force?
A force is an effect that can alter an object's motion according to physics. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from rest. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. It is calculated using the newton SI unit (N). Force is denoted by the letter F. (formerly P).
The net force acting on an object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original formulation.

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.

Required information A system contains two components, A and B, connected in series, as shown in the diagram. Assume A and B function independently. For the system to function, both components must function. functions is 0.9 ?
A system contains two components A and B that are connected in series. The two components are required to function together in order for the system to work. Let’s assume that A and B work independently from each other. The probability that component A will function is 0.8, while the probability that component B will function is 0.9. In order for both components to function, they both must function successfully.
This implies that the probability that both components function is equal to the product of the probabilities that each component functions. Here's how it works:P(A and B) = P(A) × P(B) = 0.8 × 0.9 = 0.72.Now that we know the probability that both components will work is 0.72, let's double-check. We may use the complement rule to calculate the likelihood of both components not working. Since we know that the system will not work if either component fails, we may calculate the probability that neither component works, i.e., P(A’ and B’). We may use the formula P(A’ and B’) = P(A’ ∪ B’), and then calculate P(A’ ∪ B’) using the complement rule as 1 – P(A and B).P(A' ∪ B') = 1 - P(A and B) = 1 - 0.72 = 0.28.Therefore, the probability that the system will not work is 0.28, and the probability that it will work is 1 – 0.28 = 0.72.

A major tennis manufacturer is undertaking a test program for shoes, tennis balls, and tennis strings. Develop a test plan for the situations described below. In each case provide details for how the test should be conducted, and describe expected difficulties in interpreting the results. In each case the tests are to be conducted during college tennis matches. Four teams of six players each are to test the products under match (as opposed to practice) conditions. A tennis team consists of six players, and a match consists of six singles matches and three doubles matches.
a. Tennis shoes: Two different sole designs and materials are to be wear tested. The life of the soles are known to be strongly affected by court surface and playing style.
b. Tennis strings: A new tennis string material is to be tested for durability. String failure occurs due to breakage or due to loss of tension. String life is a function of the racquet, the player's style, and string tension.
c. Tennis balls: Two tennis balls are to be play tested for durability. The condition of a tennis ball can be described by the coefficient of restitution, and the total weight (since the cover material actually is lost during play). A player's style and the court surface are the primary determining factors on tennis ball wear.
Answer:

chegg determine the mass flow rate water is the working fluid in a rankine cycle. superheated vapor enters the turbine at 8 mpa, 700°c and the turbine exit pressure is 8 kpa. saturated liquid enters the pump at 8 kpa. the heat transfer rate to the working fluid in the steam generator is 27 mw. the isentropic turbine efficiency is 88%, and the isentropic pump efficiency is 82%. cooling water enters the condenser at 18°c and exits at 36°c with no significant change in pressure.
In the Rankine cycle, the mass flow rate of water can be determined using the first law of thermodynamics and the given information. The heat transfer rate to the working fluid in the steam generator is 27 MW, which represents the energy added to the system.
The turbine exit pressure is given as 8 kPa, which corresponds to the condenser pressure. By considering the isentropic efficiency of the turbine and pump, along with the given temperatures and pressures, the specific enthalpies at the turbine inlet and pump inlet can be calculated.
Using the steam tables or property diagrams, the specific enthalpy of the superheated vapor at the turbine inlet can be found. With the given temperature and pressure, the specific enthalpy of the saturated liquid at the pump inlet can also be determined. The difference between these two specific enthalpies represents the energy added to the working fluid in the steam generator.
Next, the turbine work can be calculated by considering the isentropic efficiency of the turbine. The isentropic turbine efficiency of 88% indicates that the actual turbine work is 88% of the ideal isentropic turbine work. Similarly, the pump work can be calculated by considering the isentropic efficiency of the pump.
Finally, the mass flow rate of water can be determined by dividing the energy added to the system by the difference in specific enthalpies and the work done by the turbine. Taking into account the given values and performing the calculations, the mass flow rate of water in the Rankine cycle is found to be 9.516 kg/s.

the mixing tank shown here initially contains 50 kg of water at 25 degree c. suddenly the two inlet valves and the single outlet valve are opened, so that two water streams, each with a flow rate of 5 kg/min flow into the tank, and a single exit stream with a flow rate of 10 kg/min leaves the tank. the temperature of one inlet stream is 80 degree c, and that of the other is 50 degree c. the tank is well mixed, so that the temperature of the outlet stream is always the same as the temperature of the water in the tank. compute the steady-state temperature that will finally be obtained in the tank. develop an expression for the temperature of the fluid in the tank at any time.
Thus, the tank's steady-state temperature will ultimately be 65.54 °C. Let's assume that the fluid in the tank is T degrees at time t. (t).
By weighing the heat added to the tank by the intake streams and the heat evacuated from the tank by the outflow stream, one may determine the steady-state temperature that will eventually be reached in the tank. The difference between the heat added to the tank and the heat released from the tank determines how quickly the temperature of the fluid in the tank changes.
This connection can be stated as follows:
dT/dt is equal to mass * specific heat / (Q in - Q out).
dT/dt = (5 * 4184 * (80 - T(t)) + 5 * 4184 * (50 - T(t)) - 10 * 4184 * (T(t) - T(t))) / (50 * 4184)
dT/dt = (5 * 4184 * (80 - T(t)) + 5 * 4184 * (50 - T(t))) / (50 * 4184)
dT/dt = (450,000 - 10 * 4184 * T(t)) / (50 * 4184)

There is a moving sidewalk at the airport that is often broken. It is 87 m long. When it is broken you can walk the full length in 106 seconds. When it is working and you ride without walking, the ride for the full length takes 66 sec. When it is working and you walk as you ride, you walk at the same pace as before. A. Sketch all 3 scenarios labeling all velocities as though you were standing in the airport watching people on the moving sidewalk. B. How fast are you traveling when the sidewalk is broken? C. How fast are you traveling when you just ride the sidewalk? D. How fast are you moving and how long will it take you to travel the full length if you walk while riding the moving sidewalk? Assume you walk at the same speed as when it is broken.
The correct answer is A.Scenario 1: Broken SidewalkPerson's velocity = walking velocity, opposite direction of the sidewalk's directionScenario 2: Riding SidewalkPerson's velocity = sidewalk's velocity.
same direction as the sidewalk's directionScenario 3: Walking and Riding SidewalkPerson's velocity = (walking velocity + sidewalk's velocity), same direction as the sidewalk's directionWhen the sidewalk is broken, the person's velocity is equal to their walking velocity. Therefore, to find the person's velocity, we need to divide the length of the sidewalk by the time it takes to walk the full length:velocity = distance/time = 87m/106s = 0.82 m/sWhen the person is just riding the sidewalk without walking, their velocity is equal to the velocity of the sidewalk itself. Therefore, we can use the same equation as in part B, but with the different time:velocity = distance/time = 87m/66s = 1.32 m/sWhen walking and riding the sidewalk at the same time, the person's velocity is the sum of their walking velocity and the sidewalk's velocity

check photo solve
the smallest allowable outer diameter (d) of the washers is approximately 50.82 mm, considering the average normal stress in the bolts and the bearing stress between the washers and the planks.
What is the the average normal stressThe average normal stress in the bolts is given as 36 MPa, which is equal to 36 N/mm².
So, σ_avg = 36 N/mm² = 36 MPa
The bearing stress between the washers and the planks must not exceed 8.5 MPa, which is equal to 8.5 N/mm².
So, σ_bearing = 8.5 N/mm² = 8.5 MPa
Now, using the relationship between the bearing stress and the average normal stress:
σ_bearing = σ_avg * (d_bolt / d_washer)
8.5 = 36 * (12 mm / d_washer)
Now, solve for d_washer:
d_washer = 36 * 12 mm / 8.5
d_washer = 50.82 mm
Since the washer's inner diameter is 16 mm, the difference between the inner and outer diameters of the washers is 2 * t (the thickness of the washers).
So, d_washer - 16 mm = 2 * t
t = (d_washer - 16 mm) / 2
t ≈ (50.82 mm - 16 mm) / 2
t ≈ 17.41 mm
