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 ...

and resist shear stress (side-to-side movement between parts). These characteristics permit parts to move up and down without sliding on and ruining the cylinder head gasket. Recognized by a ...

Here, you can easily see how the laminae slide with respect to each other in the absence of shear stress between the laminae. Beam with shear stiffness Now let's consider reconsider our laminated beam ...
