But try explaining what "torque" pulls a million pound jetliner of the ground...

Torque is the lever that lifts the weight, torque is the flywheel that turns the wheels, torque is the compression, combustion and the thrust that sends the jetliner into the wild blue yonder... you can have all the hp you want.. but without the torque, your not getting anywhere.

And just where do those examples apply on a modern jetliner? What about a Saturn V rocket? A cruise missile?

The problem with using torque is that many massive objects can move without torque. But power is universal within well, the universe.

Newton tells us Power = Force x Velocity.

I can apply it to any subject in motion from an oil tanker to the space shuttle. While torque is only applicable to rotating objects. It's a MEAN of producing power, via an important term *rpm*. But torque by itself is not power.

If I hang myself on a 100' bar I'm generating 20,000 lb-ft all day long. But I'm doing jack all... 20,000 * 0 rpm / 5252 = 0 hp.
