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. The tensile force in the cable is 8 kN.
(a) Draw the shear-force and bending-moment diagrams for beam ABCD. Note: Disregard the widths of the beam and vertical arm and use centerline dimensions when making calculations
(b) Repeat part (a) if a roller support is added at C and a shear release is inserted just left of C (see figure part b).
