At Maximum bending moment with uniformly distributed load is given by wL2 /4 and the other point it's given by P(L+L)/4.
2867025352425016192502571750091440033337500Question 5/137. From the diagram, Force M1 is used to counter the forces and make it zero. With the above condition Bending moment at C = B =0. Bending moment at A which is the maximum moment = 2 * 4 =8kN and moment at D = 2*(4-2) = 4kN. The maximum shear force is given by wL2 / 2= 2*42 /2= 16kN
