The sliders A and B are connected by a light rigid bar and move with negligible friction in the slots, both of which lie in a vertical plane. For the position shown, the hydraulic cylinder imparts a velocity and acceleration to slider A of 0.4 m/s and 2 m/s, 3 kg 05 m respectively, both to the right. Determine the acceleration of slider B and the force in the 60 bar at this instant. Fig.P2

F The retractable shelf shown is supported by two identical linkage-and-spring systems; only one of the systems is shown. A 20-kg machine is placed on the shelf so that half of its weight is supported B 300 mm 30° 30° E by the system shown. If the springs are removed and the system is released from rest, determine (a) the acceleration of the machine, (b) the D 80 mm 100 mm A 80 mm | 30° tension in link AB. Neglect the weight of the shelf 200 mm and links. 50 mm 100 mm

A 1.8-kg collar A and a 0.7-kg collar B can slide without friction on a frame, consisting of the horizontal rod OE and the vertical rod CD, which is free to rotate about its vertical axis of symmetry. The two collars are connected by a cord running over a pulley that is attached to the frame at O. At the instant shown, the velocity vA of Collar A has a magnitude of 2.1 m/s and a stop prevents collar B from moving. The stop is suddenly removed and collar A moves toward E. As it reaches a distance of 0.12 m from, the magnitude of its velocity is observed to be 2.5 m/s. Determine at that instant the magnitude of the angular velocity of the frame and the moment of inertia of the frame and pulley system about CD.
