MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
yes
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: 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.
0, bending moment is at maximum

The BM diagram can help you in the calculation of the shear force and the bending moment.
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 determine the internal shear forces and moments at any given point on a rigid body.
Cry man, cry!
Tension, Compression, Shear FOrce, Bending Moment and Torsion
in strength of material, u studied shear force and bending moment diagram for static load ( load position is fixed) but influence line diagram is used to draw shear force diagram and bending moment diagram for moving load (load position varies with distance)..
