A beam has a triangular cross-section, having altitude ”h” and base “b”. If the section is being subjected to a shear force “F”. Calculate the shear stress at the level of neutral axis in the cross section.

A beam has a triangular cross-section, having altitude ”h” and base “b”. If the section is being subjected to a shear force “F”. Calculate the shear stress at the level of neutral axis in the cross section. Correct Answer 8F/3bh

For a triangular section subjected to a shear force, the shear stress at neutral axis is = 4/3 × average shear stress = 4/3 × F/A/2 ; A = bh = 8F/3bh.
