Horsepower in inches per second?

  1. Sep 25, 2015 #1
    Hello Wizards!

    O.K. I know that 1 horsepower is generated by moving 300 lbs 100 feet in one minute.

    The question I seem unable to answer is....

    How many horsepower is generated by moving 19 lbs 1-1/2 inches in 1 second?

    Help please ( my brain is exploding )

    Best Regards,

    Bill

    How many inches in a foot? How many seconds in a minute? Just do the unit conversion.

    The way that's worded makes it sound like the 300lb is the weight of the object, not the force...

    Like a lot of things people "know", this sounds like it might be true. However, the facts get in the way of a good story.

    One horsepower = 550 foot-pounds of work done in one second, or 33,000 foot-pounds of work done in one minute.

    Whether it actually takes 300 foot-pounds of work to move 300 pounds a distance of one foot is another story.
