The bending moment M at position x m from the end of a simply supported beam of lenght L m carrying a uniformy distributed load of w Kn m-1 is given by

M = w/2 L (L-x)- w/2 (L - x)^2

show using the above expression that the maximum bending moment occurs at the mid point of the beam and determine its value in terms of w and L hide problem
