Question

The couple moment produced in the beams are called as ____________________

(a) Moment of distance

(b) Moment of line

(c) Moment of bending

(d) Bending moment

I had been asked this question during a job interview.

This intriguing question originated from Internal Forces Developed in Structural Members in section Internal Forces of Engineering Mechanics

Answer 1

Correct answer is (d) Bending moment

The best explanation: The forces are making the body tend to rotate. This is in general making the body rotate or make generate the moment in the beams. This moment is the same thing as the couple moment. But in beams it is referred as bending moment. And is again used for the designing of beams.
