Problem 4.3-14 The simply-supported beam ABCD is loaded by a weight W 5 27 kN through the arrangement shown in the figure. The cable passes over a small frictionless pulley at B and is attached at E to the end of the vertical arm. Calculate the axial force N , shear force V , and bending moment 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 centerline dimensions when making calculations.) Solution 4.3-14 Beam with cable and weight SECTION 4.3
