Maximum Shear Stress in Triangular section = Above the N. A.

Centroid is at h/3.

Mid way means h/2. Clearly mid way is above centroid and neutral axis above centroid has higher stress.

It seams Above the neutral axis.

@Neeraj.

What you said is for triangle. For rectangle it's h/2.

For shear apply formula.

τ = shear force*area* distance from neutral axis/(MI*Width).

Hence shear is inversely proportional to width.

For rectangular section h/6 distance from the neutral axis or above the neutral axis for all.

Above the neutral axis.

Any one please suggest a method to check shear for triangular section.
