Find the magnitude of the tension in each supporting cable shown below. In each case, the weight of the suspended body is 100.0 N and the masses of the cables are negligible.
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
(a) What force must be exerted by the wind to support a 2.50-kg chicken in the position shown in Figure 9.33? (b) What is the ratio of this force to the chicken's weight? (c) Does this support the contention that the chicken has a relatively stable construction? Figure 9.33
In order to lift a shovelful of dirt, a gardener pushes downward on the end of the shovel and pulls upward at distance l2 from the end, as shown below. The weight of the shovel is mg and acts at the point os application of F2 . Calculate the magnitudes of the forces F1 and F2 as functions of l1 , l2 , mg, and the weight W of the load. Why do your answers not depend on the angle that shovel makes with the horizontal?

1. A museum of modern art is displaying an irregular 426-N sculpture by hanging it from two thin vertical wires, A and B, that are 1.25 m apart. The center of gravity of this piece of art is 48.0 cm from its extremeright tip. Find the tension in each wire. Give also the FBD. Show your complete solution.
In the strict curl weightlifting event, a standing athlete lifts a barbell using only their lower arms, hinging at the elbow. The record weight is 900N. The biceps tendon connects 4.00cm from the elbow and pulls straight up, while the barbell is held 35.0cm from the elbow. Assume the weight of the forearm is negligible, and that each arm supports half the weight of the barbell. A) What is the tension in the tendon connecting the bicep to the forearm while held stationary in the position shown? B) What is the force (magnitude and direction) of the upp arm pushing on the forearm at the elbow joint?
