The figure shows a weapon called a battering ram (modern large battering rams are typically mounted on armored vehicles). The ram has a weight w, = 2500 lb, center of mass at E, and radius of gyration kE = 6.5 ft. Also let the distance between points A and B and between points C and D be 6 ft. In addition, let h 4.5 ft and d = 3 ft. Finally, let the connections at points A, B, C, and D be pin connections, and assume that the cart does not move while the ram swings. Assume that AB and CD are uniform thin rods weighing 100 lb each and that the ram is at rest with 0 = 0°. Assume that bar CD breaks suddenly, and determine the acceleration of E and the forces at A immediately after CD breaks. ram ED
