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

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.

How can anyone explain?

The maximum shear stress of a beam of triangular section occurs at middle of height.

Sreenath said:   1 decade ago
Max shear stress is at h/6 distance from the base for triangle.

Sagar said:   9 years ago
The maximum shear stress occurs at h/2, and not at the neutral axis.

AKASH JAISWAL said:   9 years ago
Max. Shear stress = 1. 5 shear stress at neutral axis (Avg.) means in rectangular section max shear is h/2 DISTANCE.

Arun kumar M said:   9 years ago
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.

Balu said:   8 years ago
Given answer is correct. In triangular section max stress occurs at h/2 from base. But NA lies near to base.

Shankha Das said:   6 years ago
NA lies h/3.
Maximum shear stress lies h/2.
So, it will above NA.
