In physics, shear stress is a stress state in which the shape of a material tends to change (usually by "sliding" forces -- torque by transversely-acting forces) without particular volume change.
The 'Shear Stress' Of It Impacts Heart Disease (February 18, 2007) -- Dutch researchers report that in mice, different types of shear stress induce the production of different soluble factors known as chemokines, and that the chemokine expression pattern influences the...

The vertical shearing stress at any point in a beam may be determined from the horizontal shearing stress at that cross-section.
V is always the absolute value of the total shear (from the V diagram) on the beam at the section being investigated (this is usually the point where the shear is greatest).
The second example illustrates that the maximum horizontal shearing stress in a rectangular beam occurs at the neutral axis.
