In class, we have used the Euler-Bernoulli theory of beams to calculate this shear stress. Recall that the E-B theory of beam assumes that beam cross sections always remain perpendicular to the ...
Under the action of a transverse load we see below how the beam deflects in the absence of shear stiffness. Focus, in particular, on the deflection at the right end of the beam, as seen below. Here, ...
