Question
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 Ib, center of mass at E, and radius of gyration kF= 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
Dare 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, 6 = 10° and the ram is swinging
forward with
= 5.5 ft/s.
-d-
ram
BE--
At this instant, determine the acceleration of E, as well as the tensions in the cords AB and CD.
The acceleration of E is a E
The tension in the cord AB is
Ib
The tension in the cord CD is
Ib
