This shear force is directly responsible for the shear stress τ on the x-face of a stress element at “a” in the positive y-direction. In class, we have used the Euler-Bernoulli theory of beams to ...

The goal is to force the beam specimen to fail in a shear mode. This can be achieved because the shear stress is independent of the support length, whereas the flexural (bending) stresses are a linear ...

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.
