What is a foot pound?
its a unit measure of torque. Torgue is equal to the cross product of the level arm vector and the force vector.
A foot pound is a measure of torque however.... 1 hp = 550 (ft*lbs)/s = 33,000 (ft*lbs)/min Horsepower is related to the time derivative of torque, but it's not exactly equal to a torque neither in units or quantity. (Torque*RPM)/5252=Horsepower (The 1/5252 changes depending on the units being used) ------------------------ (A little more on torque) Torque is the cross product of lever arm and the force, but generally in automotive terms theta is almost always 90 degrees so sin(theta)=1. So the cross product simplifies down to force * distance... Hold the end of a 1ft ruler with one hand and hang a 1 pound weight off the other end... The twisting you feel is 1 foot pound. Hope that made sense...
thanks, i get it now
