Dynamics 110 Kinetics of Rigid Bodies with Rotation – A bar with length L is released from the position shown with Find the acceleration of the θ=30°. contact point if the surface is frictionless. Solution: We begin by drawing a free body diagram of the bar. Considering force equilibrium in the x-direction gives Since for the initial position, the accelerations of points c and o are related through the ω=0 kinematic relation Combining this with the previous equation, we conclude that Considering moment equilibrium about point o gives Combining this equation with the previous one gives Author: Kennedy, T.
