Question

2 Nm

(a) 10 Nm

(b) 7Nm

(c) 8Nm

This question was addressed to me at a job interview.

My doubt is from Moment of a Force topic in section Force System Resultants of Engineering Mechanics

Answer 1

The correct option is (a) 10 Nm

For explanation: As we know that the moment is the cross product of the force and the distance between the point of contact of the force and the point about which moment needs to be calculated. Thus forming the distance vector and then crossing it with the force will give us the answer. Remember force also needs to be in the vector form for doing the cross product.
