- In rectangular section, maximum shear stress acts on the neutral axis and is zero at both top and bottom surface.
- In triangular section, maximum shear stress does not act on the neutral axis but occurs at a distance of H/2.
- Maximum shear stress at neutral axis is given as
τ = (8/3) (S/bh)
S is the shear force, b is the base and H is the height of triangle.
- Maximum shear stress at H/2 is given as
τ = (3/2) τ
avg
here, τ
avg
= (S/bH)
