A beam ABCD with a vertical arm CE is supported as a simple beam at A and D (see figure). A cable passes over a small pulley that is attached to the arm at E. One end of the cable is attached to the beam at point B. Cable B -6 ft (a) Cable B Shear release -6 ft- (b) (a) What is the force P in the cable if the bending moment in the beam just to the left of point C is equal numerically to 960 lb · ft? (Note: Disregard the widths of the beam and vertical arm and use centerline dimensions when making calculations.) Round your answer to the nearest whole number. P =| lb (b) Repeat (a) if a roller support is added at C and a shear release is inserted just left of C (see figure part b). Round your answer to the nearest whole number. P = lb
