Shear force is related to change in bending moment between adjacent sections.
As shown in figure, consider a cut-out section from a beam.
At section 1 {Area PADS}
Here I is the moment of Inertia of the entire cross-sectional area around the neutral axis.
Shear Stress Formula for Beams
The shear stress formula is obtained by modifying the shear flow formula.
