Measure the shear deformation of the block.. Determine of modulus of rigidity.. Introduction. Rubber blocks in shear force are often used on engine and in equipment mounting to isolate vibrations. They do this by absorbing shock energy by deforming. This deformation leads to a decrease in cross-section as the block lengthens, an effect described by Poisson's Ratio.. Viscous Fluids.
