Question

Consider the following beam

The magnitude of maximum value of bending moment of D due to the moving vertically downward load of 20 kN is ______ kNm.

• A. 40

Answer 1

The correct option is A 40
ILD for bending moment at D



$\therefore$ For maximum bending moment at D, keep 20 kN at C
We get, $M_D=-2\times 20=-40kNm$
$\therefore$ The magnitude of maximum bending moment at D = 40 kNm.
