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 angle of twist for a section of length L is given by the equation shown below ... shaft with material homogeneity on the cross-section, the both the shear strain and shear stress vary linearly ...
