Three rods of lengths 9 in., a= b=6 in., and c = 12 in. are welded together to form the component shown. The component is supported by eyebolts at A and C and by a shallow slot cut in a block at B. Neglecting friction, determine the reactions at A, B, and C when P = 40 lb, MA=36 lb ∙ ft, and MC = 0.
