Torque

Torque:

Measures how much a force is able to cause an object to rotate

Torque, like pressure:

Cannot be called a force itself

tau=rf

Formula for torque

Where torque(tau) is the product of an applied for(f) perpendicular to the lever arm of the rotated project:

And the length of the lever arm r, measured from the pivot point(center of rotation) or fulcrum, to the point where force is being applied

The length of the lever arm is measured in:

m or ft

Torque may therefore be measured in standard:

NM(Newton Meters) or FT LB(Foot Pound) unit

However, remember this length measurement is perpendicular to the force applied in rotating the object, not parallel:

So torque is not equivalent to work, whose nm units(more often expressed as joules) represent a force applied through distance
