Chapter 6, Problem 6.55SP
When a large rope is wrapped twice around a post, a pull of 100 lb at the free end will withstand a pull of 2 tons at the other end. What pull would the 100 lb withstand if the rope were wrapped only once around the post?

To move a heavy crate across a floor, one end of a rope is tied to it and the other end is tied to a wall 30 ft away. When a force of 100 lb is applied to the midpoint of the rope, the rope stretches so that the midpoint moves to the side by 2 ft. What is the force on the crate? Select the correct response: 400 lb 500 lb 410 lb 379 lb
