Chapter 5.2, Problem 5.2GI
In the figure below we’ve replaced one of the hands from Fig. 5.9 with a hook attaching the rope to a wall. On the right, the hand still pulls with a 1-N force. How do the forces now differ from what they were in Fig. 5.9? (a) there’s no difference; (b) the force exerted by the hook is zero; (c) the rope tension is now 0.5 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?
The following figure and situation are to be used for questions 1 to 4.
An object, attached at the origin, point O, is being pulled by three ropes, A, B, and C, as shown in the figure. The tension produced in these
ropes are as follows:
TOA: 1 500 N, along the x-y plane, 36.9" from the positive x-axis, and 53.1 from the positive y-axis
ToB: -800i +800j+400k N

In rock climbing, various rope and pulley systems have been devised to help haul up heavy loads, including injured climbers. A rescuer is hauling up an injured climber who weighs 570 NN using the rope and pulley system shown in (Figure 1). (The ropes in this figure are drawn at various angles for clarity, but you can assume they're all vertical.)
What is the tension in rope 1, the rope that the rescuer pulls on?
What is the tension in rope 2?
