Shear Stress
Shear Stress is a core engineering term. Definition, usage notes, and a practical example.
Definition
Shear stress is stress created by internal force acting parallel to a surface.
Why it matters
It is critical in pins, bolts, welds, and torsion checks.
How it is used
In a design check, first define the relevant load, dimension, material, or flow condition. Then interpret this term by its role in the formula and compare it with limits.
Shear stress = Shear force / Area
Example
If a pin load tends to slide across the section, shear stress is checked.
