1. A T-shaped bar is supported as shown below. The bar is in equilibrium. The weight of the bar can be neglected. A force, P = 100 lb. is applied at point A as shown below. Determine the x- and y- components of the reaction force at B and the reaction force at C. Ans: Bx = 90 lb →, By = 220 lb v, Cx = 90 lb , Cy = 120 lb ↑ %3D %3D %3D %3D %3D 15 in 20 in Ľ. B 10 in A 4
