The correct answer is WL/8.
See the W is capital that means total load.
In these types of cases, W represents total load.
But we know the maximum bending moment is wl^2/8.
These cases w=W where w is udl intensity and W is a total load.
Thanks.

Due to symmetric loading, reactions are equal having magnitude = WL/2.
The maximum moment will occurs at center of span because of symmetric loading.
Take moment at this point,
Maximum bending moment = (WL/2) (L/2) - (WL/2) (L/4) = WL^2/8.

Take moment at this point,
Maximum bending moment = (WL/2) (L/2) - (WL/2) (L/4) = WL^2/8.

Support reactions are Vay = wl/2 = Vby.
Cut s/n and take the moment at pont zero.
M = - (wx^2/2) +wlx/2.
Max moment at mid pnt l/2.
M = Wl^2/8.
For uniformly distributed load moment varies parabolically not linearly.

S L be the length of span kn/m total udl then we calculate maximum bending moment = force * distance.
And also half of the total udl distance then wl^2/8.
And also half of the total udl distance then wl^2/8.

It should said that total uniformly distributed load is W.

According to me, the correct answer is WL^2/8 not wl/8.

I agree that the correct answer is wl^2 / 8.
