The simply supported beam ABCD is loaded by a weight W = 27 kN through the arrangement shown in the figure part a. The cable passes over a small frictionless pulley at B and is attached at E to the end of the vertical arm. Repeat part (a) if a roller support is added at C and a moment release is inserted just left of C (see figure part b). Calculate the axial force ( ) kN, shear force ( ) kN, and bending moment ( ) kN·m at section C, which is just to the left of the vertical arm. Note: Disregard the widths of the beam and vertical arm and use cen- terline dimensions when making calculations.
