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 ...

(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 ...

In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which ...
