Question

what is shear stress in simplest language​

Answer 1

Shear stress, often denoted by τ (tau), is the component of stress coplanar with a material cross section. Shear stress arises from the force vector component parallel to the cross section of the material

$\huge\bf{Stress:-}$

Stress is defined as “The restoring force per unit area of the material”. It is a tensor quantity. Denoted by Greek letter σ. Measured using Pascal or N/m2.

$\huge\bf{Shear\:Stress:-}$

When the direction of the deforming force or external force is parallel to the cross-sectional area, the stress experienced by the object is called shearing stress or tangential stress. This results in the change in the shape of the body.
