Answer: option c)
Explanation: The moment formulae is given by
Moment = force × perpendicular distance.
Moment is zero when the applied force and distance away from the force to a turning point (center of rotation) are not perpendicular.
The perpendicular distance between the applied force and the center of rotation is the main reason for moment to be available in any system, hence that distance is called a moment arm
The perpendicular distance between the applied force and the center of rotation is called the moment arm
What is a moment?
The formula of the moment should be provided by
Moment = force × perpendicular distance.
here Moment should be zero at the time when there is applied force and distance away from the force to a turning point should not be perpendicular.
So, The perpendicular distance between the applied force and the center of rotation is the significant reason for the moment to be available in any system
