When the line of action of a force passes through the pivot point, the torque of the force is maximum.
True
False
The perpendicular distance between the pivot point and the line of action of the force is called the (a)
Torque is a vector quantity.
True
False
The SI unit of torque is (a)
The formula for calculating the magnitude of the torque is
