Chapter 6, Problem 6.54SP

A sailor wraps a heavy rope around a bollard (a vertical post) to secure a drifting ship to a pier. The sailor can apply a force of 400 N to the free end of the rope. With what force can the ship pull on the rope before another sailor will have to be called? Consider (a) one wrap, (b) two wraps, (c) three wraps. Assume a coefficient of friction of 0.35.

A heavy cask (full of wine!) sits on an inclined plane. It is held in place by a rope that is attached to the cask and to a hook further up the inclined plane (at A). The rope comes off of the cask tangent to the cask. The mass of the cask is 40 kg, and the coefficient of static friction between the inclined plane and the cask is 0.25. What is the maximum value of 0 just before the cask begins to slip? Also, what is the tension in the rope when slipping is impending? Finally, if the inclined plane became icy, and the rope didn't break as the cask slipped, what would be remarkable about the lines of action of the W, N and T force vectors once equilibrium was re-established? 0.70 m 40
A weight of 10 N resting on an inclined plane at 30° to the horizontal is connected bya string passing over a frictionless pulley at the upper end of the inclined plane. The free end of the string is connected to a weight of 20N which hangs in air. If the coefficient of friction of the inclined surface is 0.2, calculate the time taken by the hanging weight to decend by 1 m. (1) ON u=0.2 (2) 30 20N Given diagram Fig s=1m
