Question

The maximum bending moment induced in the beam loaded as shown in figure is kM, then the value of $\left|k\right|$ is

• A. 1

Answer 1

The correct option is A 1
$\sum M_c=0$

$\Rightarrow R\left(2a\right)+M+1.5M+0.5M=0$

$\Rightarrow$ $R=-\frac{1.5M}{a}i.e\frac{1.5M}{a}(\downarrow )$


So maximum bending moment = 1 M = kM
$\therefore$ $\left|k\right|$ = 1
