Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_5

6/5 The frame is made from uniform rod which has a mass \(\rho\) per unit length. A smooth recessed slot constrains the small rollers at \(A\) and \(B\) to travel horizontally. Force \(P\) is applied to the frame through a cable attached to an adjustable collar \(C\). Determine the magnitudes and directions of the normal forces which act on the rollers if (a) \(h = 0.3L\), (b) \(h = 0.5L\), and (c) \(h = 0.9L\). Evaluate your results for \(\rho = 2 \text{ kg/m}\), \(L = 500 \text{ mm}\), and \(P = 60 \text{ N}\). What is the acceleration of the frame in each case?
