SHEAR FORCE AT A DISTANCE L/1.732 BECOMES ZERO WHILE DRAWING S.F D. HENCE BENDING MOMENT BECOMES MAXIMUM THERE.

This is uniformly varying load act at 2/3 from point B. Total load is area of triangle.
M = wl/2*2l/3 M.
M = wl/2*2l/3 M.

Answer should be 2l/3 from B end.

First calculate Ra and Rb. Value of Rb=WL/6 taking section between B & A and find distance where sf is zero.
wx^2/2l-WL/6=0 x=l/√3.
wx^2/2l-WL/6=0 x=l/√3.

Answer is L/3. Maximum bending moment is at distance 2l/3 from A. So the answer is l/3 from B.

Bending moment is maximum where shear force is zero. In this case it will be at l/3 from end b.
