above the neutral axis ..in triangle cross section.

- 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) τavg

here, τavg = (S/bH)
