A simply-supported beam spanning 12m, AB=2m, AC=4m, AD=8m, AE=12m. The left and right ends are supported by roller and pin, respectively. This beam is subject to a concentrated load of 32 kN at B, a couple of 20 kNm at C and distributed loading with a density of 15kN/m from C to D.
(a)Plot the shear force and bending moment diagrams and
(b)Find the maximum bending moment and its position.
