The 1200-mm slender bar has a mass of 20 kg with mass center at B and is released from rest in the position for which is essentially zero. Point B is confined to move in the smooth vertical guide, while end A moves in the smooth horizontal guide and compresses the spring as the bar falls. Determine (a) the angular velocity of the bar as the position 8= 30° is passed and (b) the velocity with which B strikes the horizontal surface if the stiffness of the spring is 5 kN/m. 600 mm www A k 450 mm- O 600 mm The 1200-mm slender bar has a mass of 20 kg with mass center at B and is released from rest in the position for which is essentially zero.
