The figure shows a weapon called a battering ram (modern large battering rams are typically mounted on armored vehicles). The ram has weight Wr=2590 lb, center of mass at E, and radius of gyration kE=6.4 ft. Also let the distance between points A and B and between points C and D be 5.2 ft. In addition, let h= 4.4 ft, d= 2.6 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 BC are uniform thin rods weighing 82 lbs each. Assume that, at the instant shown, theta= 9.8 degrees and the ram is swinging forward with magnitude of vE= 6.8 ft/s. At this instant, determine the acceleration of the ram as well as the reaction forces at points A and C.
