Say we consider a beam made up of thin layers (laminae) aligned with the longitudinal axis of the beam, and for which the laminae can slide with respect to each other along the longitudinal axis as ...

Non-Newtonian fluids may exhibit shear thinning, where the viscosity decreases with stress; common examples include ketchups ...

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 ...
