Problem 2: The mechanism shown is one of two identical mechanisms attached to the two sides of a 90-kg uniform rectangular door. Edge ABC of the door is guided by wheels of negligible mass that roll in horizontal and vertical tracks. A spring of constant k = 600 N/m is attached to wheel B. Knowing that the door is released from rest in the position 0 = 30° with the spring unstretched, determine the velocity of wheel A just as the door reaches the vertical position. B `1.5 m C 1.5m

Problem 1: The 8-lb rod AB is attached to a collar of negligible weight at A and to a flywheel at B. The flywheel has a weight of 32 lb and a radius of gyration of 9 in. Knowing that in the position shown the angular velocity of the flywheel is 60 rpm clockwise, determine the velocity of the flywheel when point B is directly below C. A 36 in. B 12 in.
