or shear·ing stress
[sheer stres or sheer-ing stres]
- the external force acting on an object or surface parallel to the slope or plane in which it lies; the stress tending to produce shear.
- a coefficient of elasticity of a substance, expressing the ratio between the force per unit area (shearing stress) that laterally deforms the substance and the shear (shearing strain) that is produced by this force.
Also called modulus of rigidity, modulus of torsion, torsion modulus.

- See under modulus of elasticity.
- A form of stress that subjects an object to which force is applied to skew, tending to cause shear strain. For example, shear stress on a block of wood would arise by fixing one end and applying force to this other; this would tend to change the block's shape from a rectangle to a parallelogram. See also strain.
