How many foot pounds per second does a 3 horsepower engine generate?

To determine how many foot-pounds per second a 3 horsepower engine generates, it's essential to understand the relationship between horsepower and foot-pounds per second.

One mechanical horsepower is defined as equal to 550 foot-pounds per second. Therefore, to calculate the output of a 3 horsepower engine, you would multiply the horsepower value by the number of foot-pounds per second that one horsepower represents:

3 horsepower × 550 foot-pounds/second = 1650 foot-pounds/second.

This calculation shows that a 3 horsepower engine generates 1650 foot-pounds per second. The answer chosen reflects this understanding of the conversion from horsepower to foot-pounds per second.
