The figure shows a weapon called a battering ram (modern large battering rams are typically mounted on armored vehicles). The ram has a weight Wr = 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.

Figure P7.68

Let the ram be at rest with θ = 0°. Assume that the cords AB and CD are inextensible and of negligible mass. Also assume that cord AB breaks suddenly. Determine the tension in cord CD and the acceleration of E immediately after AB breaks.
