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. The distance between points A and B and between points Cand Dis 6 ft. Consider h= 4.5 ft and d= 3 ft. The connections at points A, B, C, and D are pin connections, and assume that the cart does not move while the ram swings. Assume that AB and CD are inextensible cords with negligible mass. In addition, assume that, at the instant shown, 0 = 10° and the ram is swinging forward with = 5.5 ft/s. -d- ram At this instant, determine the acceleration of E, as well as the tensions in the cords AB and CD. The acceleration of E is ae The tension in the cord AB is Ib The tension in the cord CD is Ib

Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics. 

Equilibrium of Forces

The tension created on one body during push or pull is known as force.
