The small bridge consists of an 1,800-lb uniform deck EF (thin plate), two overhead beams AB (slender rods), each having a weight of 200 lb, and a 2,400-lb counterweight BC, which can be considered as a thin plate having the dimensions shown. The weight of the tie rods AE can be neglected. If the operator lets go of the rope when the bridge is at an at-rest position, = 45¬∞, determine the speed at which the end of the deck E hits the roadway step at H, = 0¬∞. The bridge is pin-connected at A, D, E, and F.
