Question

Shear force diagram of a simply supported beam of length 4 m is shown below , the design bending moment in the beam will be ________kNm

• A. 7.7

Answer 1

The correct option is A 7.7

Shear force curve is quadratic in nature.
Maximum bending moment will occur at C.
$\therefore$ BM${}_{max}$ = Area of positive SF diagram
=$\frac{2}{3}\times 5\times 2.31=7.7kNm$
