a uniform beam of length l and mass m is inclined at an angle A uniform beam of length L and mass m is inclined at an angle of ? to the horizontal. Its upper end is connected to a wall by a rope, and its lower end rests on a rough horizontal surface. The coefficient of static friction between the beam and surface is ?s. Assume the angle ? is such that the static friction force is at its maximum value. (a) Draw a free-body diagram for the beam. (b) Using the condition of rotational equilibrium, find an expression for the tension T in the rope in terms of m, g, and ?. T = (c) Using the condition
