QUICK NOTE,
Pound-Foot (lb-ft) and Foot-Pound (ft-lb),
are NOT interchangeable / NOT the same!

The "POUND-FOOT" (lb-ft) (TORQUE/lever-energy) is a unit of torque and a vector measurement that is created by:
ONE POUND OF FORCE ACTING ON A ONE FOOT LEVER.

The "FOOT-POUND" (ft-lb) (ENERGY/linear-energy) is a scalar unit and measurement of work required to:
MOVE A ONE POUND OBJECT, ONE FOOT OF LINEAR DISTANCE.
