Answer:This may help you
Explanation:
The bending stress (σ) is defined. M is the bending moment, which is calculated by multiplying a force by the distance between that point of interest and the force. c is the distance from the NA and I is the moment of inertia.
Bending Stress may be defined as the stress developed in beam or any structural member due to pure bending(it occurs when couple occurs on both the ends of beam) in a simple manner.
The maximum stress occurs at the surface of the beam farthest from the neutral axis.In order to calculate maximum surface stress, you must know the bending moment, the distance from the neutral axis to the outer surface where the maximum stress occurs and the moment of inertia.
