The bending moment M, along a beam of length L (m), with a uniformly distributed load of w ( kN/m), is given by:
M = wLx - wx2 where x is the distance measured
2 2 from one end

When L = 8 and w = 4, M = 16x - 2x2
Determine:
(a) the maximum value of M (at the centre of the beam)

(b) the values of x when M = 21
