Re: [alfa] Talk about Torque

[bblair@xxxxxxxxxx]

Actually,  it is not lbs/ft,  but pound-foot that is the accurate term for 
torque,  the foot-pound is indeed a measurement of work.

"The unit of torque is the pound-foot or ounce-inch. Do not confuse this 
with foot-pounds, which is the measurement of work. Many times in referring 
to torque, tools are marked in foot-pounds. While this use of foot-pounds 
is technically incorrect, common usage has made it acceptable. "
