Plain English Meaning
It's a way of measuring how quickly work gets done. One foot-pound per minute means lifting a one-pound weight up by one foot, taking one minute to do it.
Full Definition
A unit of mechanical power equal to the work done when a force of one pound moves an object one foot in one minute. It expresses how fast work is being performed, not just how much work is done.
Context Anchor
Seen in airplane performance discussions when explaining power and horsepower; one horsepower equals 33,000 foot-pounds per minute.
Derivation
A 'foot-pound' is the amount of work needed to lift one pound through a distance of one foot. Adding 'per minute' turns that work measurement into a rate -- work over time -- which is the definition of power.
Why Pilots Care
Expresses engine power in a form that directly relates to climb performance and thrust available for a given aircraft weight.
Grounding Statement
If a machine lifts one pound upward by one foot in one minute, it has done work at a rate of one foot-pound per minute.
Intuition Check
Do not read “foot-pound” here as just a twisting force or as a weight. With “per minute,” it means power: how fast work is being done.
Example Sentence 1
One horsepower equals 33,000 foot-pounds per minute, so a 200-horsepower engine can produce 6,600,000 foot-pounds of work each minute.
Example Sentence 2
Climb rate improves when the engine delivers more foot-pounds per minute than needed to overcome drag and weight.
