Pully A of the treadmill is driven by a motor that can supply a moment M_A = 200 in.lb. Pully B is frictionless, and its bearing slides in a frictionless slot where force P tensions the belt. Both Pulleys A and B have 1.5 in, radius and the coefficient of static friction between pulley A and the belt is 0.3. Determine the smallest value of P needed to prevent slip between pulley A and the belt.
