A single-block brake has the dimensions: cast-iron wheel of D =15 in, a = 32.5 in, c =10.5 in, e= 6.5 in width of contact surface = 2 in. The brake block lined with molded asbestos, subtends 75º, symmetrical about the center line; it is permitted to absorb energy at the rate of 0.4 hp/in², n = 200 rpm. Assume that p is constant. Compute a) PVm and the approximate braking torque, (b) the force W to produce this torque, (c) the mechanical advantage
