If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence of ...

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 ...

But there's more too it than that! We'll start by defining viscosity using Newton's Law of Viscosity, that describes the linear relationship between the shear stress in the fluid and the strain rate, ...

When blood moves through your body, it exerts a frictional force on the walls of blood vessels. This force, known as fluid ...

Some notoriously difficult-to-treat infections may not be as resistant to antibiotics as has been thought, according to new ...
