A ladder is leaning against a vertical wall, and both ends of the ladder are at the point of slipping. The coefficient of static friction between the ladder and the horizontal surface is μ1 = 0.135 and the coefficient of friction between the ladder and the wall is μ2 = 0.103. Determine the maximum angle α with the vertical that the ladder can make without falling on the ground. α =

In the figure below, a 70 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 width w = 0.20 m, and the center of mass of the climber is a horizontal distance d = 0.40 m from the fissure. The coefficient of static friction between hands and rock is μ1 = 0.60, and between boots and rock it is μ2 = 1.7. (a) What is the least horizontal pull by the hands and push by the feet that will keep the climber stable? N (b) For the horizontal pull of (a), what must be the vertical distance h between hands and feet? m (c) If the climber encounters wet rock, so that μ1 and μ2 are reduced, what happens to the answers to (a) and (b)? (Select all that apply.) The force in part (a) increases. The force in part (a) decreases. The force in part (a) doesn't change. h increases. h decreases. h does not change.

In the figure a 56 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 width w = 0.10 m, and the center of mass of the climber is a horizontal distance d = 0.40 m from the fissure. The coefficient of static friction between hands and rock is μ1 = 0.40, and between boots and rock it is μ2 = 1.30. The climber adjusts the vertical distance h between hands and feet until the (identical) pull by the hands and push by the feet is the least that keeps him from slipping down the fissure. (He is on the verge of sliding.) (a) What is the least horizontal pull by the hands and push by the feet that will keep the climber stable? (b) What is the value of h?

In the figure a 51 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 width w = 0.20 m, and the center of mass of the climber is a horizontal distance d = 0.25 m from the fissure. The coefficient of static friction between hands and rock is μ1 = 0.40, and between boots and rock it is μ2 = 1.20. The climber adjusts the vertical distance h between hands and feet until the (identical) pull by the hands and push by the feet is the least that keeps him from slipping down the fissure.
