Strength of Materials
21.
Which of the following statement is wrong?
In the theory of simple bending, the assumption is that the plane sections before bending remains plane after bending.
In a beam subjected to bending moment, the strain is directly proportional to the distance from the neutral axis.
At the neutral axis of a beam, the bending stress is maximum.
The bending stress in a beam is inversely proportional to the section modulus.
Answer: Option

Answer is D because by using flexural formula it is found that stress is inversely proportional to section modules.
