One horsepower (1 hp) is equal to how many foot-pounds of force per minute?

30,000 feet pounds
33,000 feet pounds
36,000 feet pounds
40,000 feet pounds

The correct answer is: 33,000 feet pounds

One horsepower is defined as the ability to do work at a rate of 33,000 foot-pounds per minute. This measurement originates from the work of James Watt, who sought to convey the power of steam engines in a way that was relatable to the capabilities of horses, which were commonly used for labor at that time. The figure was derived from his calculations of how much work a horse could perform in a given period, leading to the conclusion that 33,000 foot-pounds of force per minute is equivalent to one horsepower. Understanding this conversion is vital in various engineering and mechanical applications, as it allows for the comparison of power outputs across different systems and machines. Knowing that one horsepower equals 33,000 foot-pounds can help in estimating the performance of pumps, motors, and other equipment that engineers might encounter.
