A winch for raising and lowering an 150 lb ball is supported by a ball-and-socket joint at A and a smooth journal bearing at B, as shown below. The bearing at B is oriented in such way that it only provides force support reactions (i.e. no moment supports at B). A winch for raising and lowering an 150 lb ball is supported by a ball-and-socket joint at A and a smooth journal bearing at B, as shown below. The bearing...
The boom AB is held in equilibriuum by a ball-andsocket joint at A and a pulley and cord system as shown. Determine the x, y, z components of reaction at A and the tension in cable DEC if F=-1500k lb. (Note that pulley at E is at the coordinates x = 0, y = 8 ft and z = 1 ft.) 2.

Consider a boom with the attached load. Point A is a ball and socket joint. y 6 ft 1. 6ft . 4ft 1 840 lb (a) Draw a free-body diagram for the boom. (b) Write down the moment equilibrium equation.
Boom AC has negligible weight and is in equilibrium. The boom is supported by cables at D and E and a ball-and-socket joint at A. The suspended crate weighs 114 lb. What is the tension (lb) in cable BDC? What is the tension (lb) in cable CE? What is the x component of the reaction (lb) (exerted on the boom by the wall) at A? What is the y component of the reaction (lb) at A? What is the z...
