Shear force:
- It is defined as the algebraic sum of all the vertical forces, either to the left or to the right-hand side of the section.
Bending moment:
- It is defined as the algebraic sum of the moments of all the forces either to the left or to the right of a section.
Calculation:
As there is no vertical and horizontal load acting on the beam, the Vertical and horizontal reaction at fixed support is zero.
The FBD of the beam is as shown in the figure.
VA = 0 = HA
The SFD and BMD of the beam are shown in the figure.
So the bending moment at the center is M kN-m and the shear force at the center is zero.
