The collars A and B weight 20 lb and 30 lb, respectively. Neglect the friction between collar B and the bar. The coefficient of static friction between collar A and the bar is 0.6. Assuming equilibrium, determine the friction force exerted on collar A. Is the coefficient of static friction at A large enough for the system to remain in equilibrium? Justify your answer. A 35-kg disk rests on an inclined surface for which mu s =0.2. Determine the maximum...
Problem 1 -Addition of a System of Coplanar Forces (15 pts) Force F acts on the frame such that its component acting along member AB is 600 Ib, directed from B towards A, and the component acting along member BC is 500 lb, directed from B towards C. Determine the magnitude of F and its direction &. Set60P
Problem 15.83 Part A The 12-lb collar B is at rest, and when it is in the position shown the spring is unstretched. Another 1-1b collar A strikes it so that B slides 4 ft on the smooth rod before momentarily stopping. The coefficient of restitution between A and B is e = 0.4. (Figure 1) Determine the velocity of A just after impact measured to the left. Express your answer to three significant figures and include the appropriate units....
