The section modulus of a circular section about an axis through its c.g. is
Bending moment at any point is equal to the algebraic sum of
Moment of a beam is defined as its section modulus multiplied by
The point of contra-flexure occurs only in
Correct Answer :- b
Explanation : In an overhanging beam case, one or both of its ends freely extended over the supports. The loading's are applied at the ends. The maximum stress is located at the center.
When we compared with above options we will get least bending stress in overhanging beams.
