Problem 1 The collars A and B weight 20 Ib and 30 Ib, respectively. Neglect the friction between collar B and the bar. The coefficient of static friction between collar A and the bar is 0.6. (a) Assuming equilibrium, determine the friction force exerted on collar A. (b) Is the coefficient of static friction at A large enough for the system to remain in equilibrium? Justify your answer.
