This equation is know as the flexure formula. Next we look at shear stresses, which act parallel to the beam cross-section, and can be represented by a shear force. These vertical shear stresses ...

(Think a deck of playing cards.) 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 ...

Stress distribution on the shaft cross-section For the solid cross-section shaft with material homogeneity on the cross-section, the both the shear strain and shear stress vary linearly with radial ...
