The bending moment equation, as a function of distance x measured from the left end, for a simply supported beam of span. L m carrying a uniformly distributed load of intensity w N/m will be given by:

A) \[M=\text{wL/2}\,\,(L-x)-\text{W/2}\,\,(L-x)N.m\]

B) \[M=\text{wL/2}x-\text{w}{{x}^{\text{2}}}\text{/2}-N.m\]

C) \[M=\text{wL/2}\,\,{{(L-x)}^{2}}-\text{w/2}\,\,(L-x)-N.m\]

D) \[M=\text{w}{{x}^{\text{2}}}\text{/2}-\text{wL}x\text{/2}N.m\]
