If the forces acting on the couple are in the same direction, that is they are not in the opposite direction as always they are, then?

(a) The direction of the forces doesn’t determine the moment

(b) The couple moment will be maximum

(c) The couple is not possible

(d) No change occurs

This question was addressed to me in an interview.

My question is based upon Moment of a Couple topic in division Force System Resultants of Engineering Mechanics

Best answer
Correct option is (c) The couple is not possible

Explanation: The forces are always in the opposite direction for the couple moment. But if they don’t act like the same, that is they change their directions and align themselves in the same direction then the couple is not possible.
