What does Shear Stress mean?
shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress .
What Physics Says:
By the language of Physics, shear stress is a stress state in which the shape of a material tends to change (usually by "sliding" forces -- torque by transversely-acting forces) without particular volume change.
EASY TO KNOW :
Symbol & Unit
Usually Shear Stress is dinoted by :
Unit : Pascal
TYPES
Basically there are 2 types of Shear Stresses
a) Horizontal Shear Stressb) Transverse Shear Stress
Horizontal Shear Stress
How it works in a wooden beam
Shear Stress on Element
Shear Stresses in Beams
Formulae:
From figure,we can notice that,a) There will be Shear Stresses acting at every cross section of the beam and the resultant shear stress at every cross section what gives a shear force.b) At top phase the shear stress(horizontal) is tends to zero .
