Main Question or Discussion Point

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.
