Shear stress
Shear stress is a stress state where the stress is parallel or tangential to a face of the material, as opposed to normal stress when the stress is perpendicular to the face. The variable used to denote shear stress is τ (tau).
The formula for shear stress in a beam is:
- V = shear force at that location
- Q = first moment of area
- t = thickness in the material perpendicular to the shear
- I = second moment of area of the cross section.
