Problem 45P

Mountain Climbing. Mountaineers often use a rope to lower them-selves down the face of a cliff (this is called ?rappelling?). They do this with their body nearly horizontal and their feet pushing against the cliff (?Fig. P11.45?). Suppose that an 82.0-kg climber, who is 1.90 m tall and has a center of gravity 1.1 m from his feet, rappels down a vertical cliff with his body raised 35.0° above the horizontal. He holds the rope 1.40 m from his feet, and it makes a 25.0° angle with the cliff face. (a) What tension does his rope need to support? (b) Find the horizontal and vertical components of the force that the cliff face exerts on the climber’s feet. (c) What minimum coefficient of static friction is needed to pre-vent the climber’s feet from slipping on the cliff face if he has one foot at a time against the cliff?
