5wl^4/584. = 5wl^3/48.

@Asif, I think your answer is correct.

But the answer should be wl^2/32,
Because for uniform loading, BMD will be parabolic.

Anyone Can explain it properly?

@Roy:

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

Thanks for better explanation @Roy.

Roy said:   8 years ago
Ra+RB+5wl/8=wl so,2x+5wl/8=wl or,x=3wl/16. So, Ra=RB=3wl/16 @Anoop.

Anoop said:   8 years ago
Can anyone tell how reactions are 3wl/16 on each end?

Roy said:   8 years ago
Thanks @Asif.
