Question 26
H

In the equation M=FdM = FdM=Fd, why is d d\,d defined as the perpendicular distance from the pivot to the line of action of the force?

[1]
A

Because a force always acts at right angles to the object that it turns

B

Because it is the shortest distance between the pivot and the moving object

C

Because only the part of the distance along the force has a turning effect

D

Because only the part of the force at right angles to the arm has a turning effect
