Generally, maximum shear stress occurs at the neutral axis. But the triangular section is an exception for that. In which maximum shear stress occurs at the middle of the height i.e. at h/2.

For every beam, the neutral axis plane where bending stress is zero and shear stress is maximum. For triangle, it h/3 from the base.

Max. Shear stress = 1. 5 shear stress at neutral axis (Avg.) means in rectangular section max shear is h/2 DISTANCE.

Given answer is correct. In triangular section max stress occurs at h/2 from base. But NA lies near to base.

Neutral axis lies at h/3 from bottom and max shear stress occurs at h/2 from bottom.

The maximum shear stress occurs at h/2, and not at the neutral axis.

Maximum shear stress occurs above NA at h/2 from the top. Thank you.

NA lies h/3.
Maximum shear stress lies h/2.
So, it will above NA.
Maximum shear stress lies h/2.
So, it will above NA.

Max shear stress is at h/6 distance from the base for triangle.
