The bent rod in Fig. a is supported at A by a journal bearing, at D bya ball-and-socket joint, and at B by means of cable BC. Using onlyone equilibrium equation, obtain a direct solution for the tension incable BC. The bearing at A is capable of exerting force componentsonly in the z and y directions since it is properly aligned on the shaft.In other words, no couple moments are required at this support.1mB.0.5 mFree-Body Diagram. As shown in Fig. b, there are six unknowns05 mEquations of Equilibrium. The cable tension Tg may be obtaineddirectly by summing moments about an axis that passes throughpoints D and A.

Tension in BC needs to be calculated

The bent rod in Fig. a is supported at A by a journal bearing, at D by a ball-and-socket joint, and at B by means of cable BC. Using only one equilibrium equation, obtain a direct solution for the tension in cable BC. The bearing at A is capable of exerting force components only in the z and y directions since it is properly aligned on the shaft. In other words, no couple moments are required at this support.
