So how does a point moment affect the shear force and bending moment diagrams? Well. It has absolutely no effect on the shear force diagram. You can just ignore point C when drawing the shear force diagram. When drawing the bending moment diagram you will need to work out the bending moment just before and just after point C: The illustration above could be much clearer.

Beam in any structure bears huge load which tries to bend the beam and beam support the structure by resisting the bending produce by the load. Ability of the beam to resist the load depends on the type of beam, material of beam and shape of beam, S Timoshenko (1940). Using these integration rules makes the calculation of the deflection of Euler-Bernoulli beams simple in situations where there are multiple point loads and point moments. The Macaulay method predates more sophisticated concepts such as Dirac delta functions and step functions but achieves the same outcomes for beam problems.
