Ok, I know the answer, I just was just wondering have you ever asked yourself that question?

The answer is written below in white. Highlight it and check if your answer was correct AFTER you submit your post ..


ONE HORSEPOWER IS:

THE EFFECT OF LIFTING 75 kgs - ONE METER - STRAIGHT UP - IN ONE SECOND.

So, if you can do that (I doubt you could), you produce the whopping amount of a single horsepower :D

Good to know, to impress the petrolheaddudes you meet at a cocktail party :)

A horsepower is equivalent to the amount of work a one horse can do in an hour

edit: Yes, continuously for an hour... (isn't it?)
 
its i think somewhere around doing 750 watts of power. Its been a little while since I took physics, but i think that is right. Power is the rate of doing work, where work is force x distance. That sounds right, but i might be wrong.

Depends where you measure it from I suppose. If you allow me to take lifting position before starting the clock, I'll do it. Again do you want me to just lift it or you want it on straight arms?? Althought doing 60 reps in 1 minute would be impossible, even for UKD.

Attach a pulley to the ceiling, pull a rope through the pulley that's attached to the 75 kg weight, and once you're in motion at 1 meter per second, then you're generating one horsepower. That's not difficult. Simply lifting a 75 kg weight off the floor one meter in one second takes a lot more than one horsepower, including overcoming inertia, the effort to hold onto the weight, etc.

Here's another way to do it: Hold enough weight in your arms so that your total weight is 75 kg, and then climb stairs. If you can climb stairs at 1 meter per second, then you're generating one horsepower. Most people in good physical shape can do this. (If you already weigh more than 75 kg, then make the total weight 150 and then it's one horsepower for every half meter per second.)

I can clean more than 75kgs and each one of them happens in much less time than 1 second.

and its 0.74 kW to every Hp. That figure also changes depending on what type of horsepower you are using.
 
So what is "torque?" :D

Horsepower or pferdstaerke was just a marketing tool used to convince horse owners to buy automobiles. It still is a marketing tool because so many people are familiar with it. Engineers and car nuts use kilowatts now. Japanese car brochures have power in kW and Nm with the old units of ps and kg-m in parenthesis.

Horsepower is just a comparitive measure of power. Even though a car may have 500hp, it doesn't mean it has that much power available at 1500rpm. It's just the maximum peak on a curve. Every car has a different curve. So those max power numbers really don't tell you the whole story.
