1.A window washer weighing 771.1 N is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 299.4 N and is 4.727 m long. What is the force in each rope when the window washer stands 1.4 m from one end?

4.1.M, a solid cylinder (M=1.63 kg, R=0.111 m) pivots on a thin, fixed, frictionless bearing. A string wrapped around the cylinder pulls downward with a force F which equals the weight of a 0.570 kg mass, i.e., F = 5.592 N. Calculate the angular acceleration of the cylinder.
