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 ...

If there are no shear stresses present ... or simply the fluid viscosity, and it is a material property of the fluid. Fluids which obey this linear relationship between stress and strain rate are ...

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 ...
