Shear stresses vary quadratically with the distance y1 from the neutral axis. The maximum shear stress occurs at the neutral axis and is zero at both the top and bottom surface of the beam.

If the beam is cantilever then compressive stress developer at the bottom layer.

Top layer will be subjected to max compressive stress and bottom layer will be subjected to max tensile stress. Refer pg :- 293, Strength of materials by R.K.Bansal.

Please explain it, how the compressive stress developed in the bottom layer?

Asif Iqbal said:   4 years ago
Top layer is the Correct answer.

Ankush said:   4 years ago
It totally depends on the type of loading.

Rajendra Sharma said:   4 years ago
During sagging compression will take place at the top layer correct answer is A.

Tensile force and tensile stressed are different and opposite to each other.

Aman Gupta said:   5 years ago
This is only true if the beam is simply supported for cantilever beam with TSL the answer will be opposite.

Agreed @Navaj Mulla.
