A beam is supported at the two ends and is uniformly loaded. The bending moment `M` at a distance `x` from one end is given by `M=(W x)/3-W/3(x^3)/(L^2)` . Find the point at which `M` is maximum.

Explanation

`M=W/3x−W/3{x^3}/{L^2}`


On differentiating, we get


`{dM}/{dx}=W/3−W{x^2}/{L^2}`


`{dM}/{dx}=0`
