A frame consists of two members (ABC and DC) and two identical pulleys with radii r = 3 in. The frame supports an applied force F= 2900 lbf and is held in equilibrium by fixed pins at A and D and by pins at points B and C. The dimensions of the frame are given as L = 30 in and h = 26.25 in. Determine the support reactions at pins A and D and the force components at pin B. Note: Express answers as magnitudes only and ignore signs/directions.
