An ideal truss has pin joint connections, allowing laod to be taken only in tension and not in bending or shear.
In reality, truss joints are not pinned, and do carry some moment and shear, but because tensile stiffness dominates, the moments and shears are small and called secondary.
There is no relationship. If the only tool used not just cut a piece to be bent.

the shear force diagram and the bending moment diagram are two separate diagrams each depicting their respective quantities.shear force and bending moment diagrams are extremely important as these two diagrams give what is needed of the beam that is to be designed. the procedure of sectioning the beam and finding the system of forces at the section is the most fundamental approach. for example the bending moment diagram can show at one glimpse the point of beam which is going to experience the maximum loading conditions and this point can be selected as the minimum requirement of the beam.
You can find these diagrams online. A simple image search can help to bring them up and you can choose the one that best meets your needs.
It is the force which act tangentially to the surface
They don't always become a curved shape. A SFD will only become a curved shape if you have a distributed load that is changing over time. A BMD will only become a curved shape if the related shear force diagram is changing over time (not a flat line) however because the SFD is the integral of the force applied and the BMD is the integral of the SFD, generally as you keep going to a higher order, you will start getting more curvy lines.
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.
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.
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

a simple definition " IT'S A COUPLE OF FORCE HAVING EQUAL MAGNITUDE BUT OPPOSITE IN DIRECTION & HAVING VERY LESS DISTANCE BETWEEN THEM"
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.
