A Ladder of length L = 5 m leans against a frame house at an angle @ = 70 degrees. Frictionless contacts occurs with a wall of height h = 3.9 m. The ladder has a mass mj; = 18kg. The service worker who must climb the ladder has a mass of ms = 65 kg Assume the contact point with the ground has a coefficient of friction between the ladder footing and the ground of u, = 0.44. Compute the friction force needed to keep the ladder in equilibrium when the worker is at the top of the ladder. What is the maximum friction that can be supported in this configuration?
