@Ram.
The equation will be wL^2/32. Substitute W=wL, Final equation will be WL/32.
The equation will be wL^2/32. Substitute W=wL, Final equation will be WL/32.

Can anyone tell how reactions are 3wl/16 on each end?
Roy said:

Ra+RB+5wl/8=wl so,2x+5wl/8=wl or,x=3wl/16. So, Ra=RB=3wl/16 @Anoop.

@Roy:
(3wl/16)*(l/2)-(w*l/2)*((l/4) = Wl/32(ans).
(3wl/16)*(l/2)-(w*l/2)*((l/4) = Wl/32(ans).
