Given: A mechanism is made up of links AB and BD, with point A being pinned to ground and point B being a pin joint connecting links AB and BD. A slider is connected to BD at pin D with the slider being constrained to move on a circular path with a radius of R. At the position shown below, link AB is vertical, link BD is horizontal and D is directly above point 0. At this position, D is...

The slider of mass m1 is released from rest in the position shown and then slides down the right side of the contoured body of mass m2. For the conditions m1-0.69 kg, m2 = 3.32 kg and r = 0.52 m, determine the absolute velocities of both masses at the instant of separation. Velocities are positive if to the right, negative if to the left. Neglect friction. n1 mg Answers: v1 = m/s V2 m/s
