Shear Stress in Design of Keys Formulas

Shear Stress is force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. And is denoted by 𝜏_{flat key}. Shear Stress is usually measured using the Newton per Square Millimeter for Stress. Note that the value of Shear Stress is always positive.

FAQ

What is the Shear Stress?

Shear Stress is force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. Shear Stress is usually measured using the Newton per Square Millimeter for Stress. Note that the value of Shear Stress is always positive.

Can the Shear Stress be negative?

No, the Shear Stress, measured in Stress cannot be negative.

What unit is used to measure Shear Stress?

Shear Stress is usually measured using the Newton per Square Millimeter[N/mm²] for Stress. Pascal[N/mm²], Newton per Square Meter[N/mm²], Kilonewton per Square Meter[N/mm²] are the few other units in which Shear Stress can be measured.
