Two identical 20.0-kg balls, each 25.3 cm in diameter, are suspended by two 35.0-cm wires as shown in the figure (Figure 1). The entire apparatus is supported by a single 18.0-cm wire, and the surfaces of the balls are perfectly smooth. Find the tension in the top wire. Find the tension in each of two bottom wires.

A bag of cement weighing 525 N hangs in equilibrium from three wires as suggested in the figure below. Two of the wires make angles ?1 = 61.0° and ?2 = 42.0° with the horizontal. Assuming the system is in equilibrium, find the tensions T1, T2, and T3 in the wires. T1 = N T2 = N T3 =.

A 1200-kg car is held in place by a light cable on a very smooth (frictionless) ramp, as shown in the figure (Figure 1). The cable makes an angle of 31.0 above the surface of the ramp, and the ramp itself rises at 25.0 above the horizontal. Find the tension in the cable and how hard does the surface of the ramp push on the car?

If you were performing this experiment in an in-class laboratory, you would be given one or more small iron balls. These would be utilized with a variant of the Free-Fall apparatus shown in the graphic below.        (INSERT PICTURE HERE)                     You would first raise the upper black clamp to the desired height above the middle clamp. Then you would place the ball firmly in the upper clamp. Next, you would turn on the timer and adjust its initial reading to zero. After you release the ball, it falls towards the middle clamp. When it encounters this clamp, the timer stops and you can read the time of fall.             Results are usually within 10% of the standard value of g. Here, in this online version, I will supply values of height (h) and time (t). First, calculate the average time (tav) for each height and use it as described next. You will use the third equation above to calculate the value of gravitational acceleration (g) in each case. Then, you will determine the…

A 3 meter long beam with weight 300 N is supported by a hinge at the wall and a cable as shown. A 300 N block is positioned along the beam at a distance x from the wall. If the breaking strength of the cable is 500 N, what is the maximum value of x? Explain all steps

You hang a light in front of your house using an elaborate system to keep the 12-kg object in static equilibrium (Figure 1). What are the magnitudes of the forces that the ropes must exert on the knot connecting the three ropes if θ2 = 63∘ and θ3 = 45∘?

A staging that weighs 390 N supports two painters, one 290 N and the other 340 N. The reading in the left scale is F = 460 N. 460 F, What is the reading F, in the right hand scale? Answer in units of N.

Consider a pulley system of the type shown in the figure above. Suppose that the upper pulley has no mass and the lower two pulleys have a total mass of  9.1 kg; the block attached to the lower pulleys represents a car engine of mass 115kg . a) What is the tension T  in the rope? Assume that all sloped segments of the rope are vertical. b) What force does the ceiling exert on the upper pulley, assuming you pull straight up on the rope?

A cubical box (equal side lengths) of mass 1.7 kg (outline shown in blue in the figure) is supported at an angle = 16 degrees relative to a horizontal surface. The cable supporting the box is at an angle perpendicular to the in-plane diagonal of the box (shown as a dotted line). What is the minimum coefficient of static friction between the box and the horizontal surface such that the box will not slide? cable 0 + 45° Ө
