Concept:

A simply supported beam with span L and centered load P is,

RA + RB = P      ---(1)

∑MB = 0

The BM will be maximum on the point at which shear force changes its sign.

So the value of bending moment at a distance x = L/2 is:

Calculation:

Given:

P = 8 kN, L = 4 m

Maximum bending moment,
