(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 ...

Shearing machines are multipurpose devices used in the cutting of alloys and other sheet metal. Some shearing machines use a scissor-like, angular shear action to cut metal into sheets or strips.

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 ...
