A 73.7 kg rock climber is in a lie-back climb along a fissure, with hands pulling on one side of the fissure and feet pressed against the opposite side. The fissure has a width w = 0.215 m, and the centre of gravity of the climber is a horizontal distance d = 0.377 m from the fissure. The coefficient of static friction between the hands and the rock and between the boots and the rock is 0.488. The climber wants to preserve their strength. At what distance, h, should they separate their hands in feet such that they only apply the minimum force necessary via their hands to keep from slipping? HINT: Start by analyzing the problem with Newton's 1st Law: Fnet,x = 0 and Fnet,y=0. You can use these equations to find the force necessary to prevent slipping. Now, express the conditions of equilibrium: net torque = 0. You can use this to find h. Once again, a well-chosen pivot can substantially simplify this problem! Your Answer:
