MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
a simple definition " IT'S A COUPLE OF FORCE HAVING EQUAL MAGNITUDE BUT OPPOSITE IN DIRECTION & HAVING VERY LESS DISTANCE BETWEEN THEM"
Shear is the rate at which bending moment changes or shear is its derivative with respect to span. The integral, bending moment, goes through a maximum when shear goes from positive to negative or vice-versa.
To calculate the bending moment of any point:WL/2 x X - WX x X/2W = WeightL = Length of beamX = distance
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
On SFD's and BMD's: The shear force will be 0, the shear force is the derivative of the bending moment at a point on shear force and bending moment diagrams. Otherwise: It depends on the loading.
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
Shear force is the force perpendicular to the axis of an object, causing it to shear or slide. Bending moment is the measure of the bending effect of a force applied to an object, causing it to bend or deform. In essence, shear force is the force that tends to make a body slide or cut, while bending moment is the force that tends to make a body bend.
Shear Force: Sum of all Vertical Forces Whose acting on a Beam but Sum of all vertical Forces must be equal to Zero. Bending Moment: The Product of Force And Displacement is known as Bending moment.
I also searching for same..
The BM diagram can help you in the calculation of the shear force and the bending moment.

To determine the internal shear forces and moments at any given point on a rigid body.
Cry man, cry!

Ah, the point of contraflexure is a special place where the shear force is zero. It's like a little moment of balance and harmony in our structural world. Just imagine a gentle stream flowing peacefully through the woods - that's the feeling we get when we reach the point of contraflexure.
