The general expression for the B.M. of a beam of length l is the beam carries
a uniformly distributed load w/unit length
a load varying linearly from zero at one end to w at the other end
an isolated load at mid span
none of these.
Answer: Option
No answer description is available. Let's discuss.

Taking moment at a point Z, X distance from either support A or B gives: (Wx^2/2)-(WL/2)*x.

Wx^2/2--------------> udl component.
(WL/2)*x-------------> reaction/support component.

Take a section at X distance from the end A of the beam.

Ra=Rb= wl/2.

Calculate moment at X distance from A.
Mx = Ra . x - w . x . x /2 = wlx/2 - w x2/2.
