Answer 1

Answer:

The value of  $R_{a}$ = $\frac{w L}{2}$

The value of $R_{b}$ = $\frac{w L}{2}$

Step-by-step explanation:

From the figure

$R_{a}$ + $R_{b}$ = $w L$ ------- ( 1 )

Take moment about A

$R_{b}$ × L = $\frac{w L^{2} }{2}$

$R_{b}$ = $\frac{w L}{2}$

Put the above value in equation (1) we get,

$R_{a}$ = $w L$ - $\frac{w L}{2}$

$R_{a}$ = $\frac{w L}{2}$

Thus the value of $R_{a}$ = $\frac{w L}{2}$

The value of $R_{b}$ = $\frac{w L}{2}$
