Two bodies A and B, each weighing 96.6 lb, are connected by a rigid bar of negligible weight attached to them at their gravity centers. The coefficient of friction at the wall and floor is 0.268 if the bodies start from rest at the given position, determine the acceleration of B at this instant. Simplify the solution by creating dynamic equilibrium and taking a moment summation about the intersection of the wall and floor reactions. Explain why these reactions pass through the gravity center of B and A respectively.
