This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear ...

The transverse load P will produce a shear force V in the positive y direction on a mathematical cut through the beam at point “a”. This shear force is directly responsible for the shear stress τ on ...

CONCLUSION: Shear stresses play an important role in the Euler-Bernoulli theory for the bending of beams when shear force resultants exist at a given cross section.
