Question
a_ draw a fully FBD
b_ solve for the forces acting in all three cables and the ball and socket joint which support the L-shaped bar?
2) An oddly shaped bar ABCE is in equilibrium in the x-it plane. The length of the bar from A to B is LI, and the length of the bar from B to C is 1.2, and the length of the bar from C to E is L3. A vertical load, P is applied to point G along the portion of the bar parallel to the x axis at a distance of 1.4 from point B. The bar is then held in equilibrium by a ball and socket joint at A. and three cables. Two cables BD and CD arc secured to point D on the wall in the y-z plane, while cable EF is secured to point F on the wall in the xy plane. The weight of the L shaped bar is negligible compared to the load.
