You guys that are probing around at the 1/4 to 1/2 hp mark are probably close. We humans are pretty weak in the grand scheme of things!!

Also, a dyno probably couldn't measure that small, nor could we spin it fast enough.

 

Power equals force times velocity. So if someone lifted a 300 lb weight straight up 2 feet in only 1 sec, then the power would be (300lbs)(2ft/sec)=600ft-lbs/sec. Now one horsepower equals 550 ft-lb/sec. So this would be 600/550=1.09 horsepower. I'm not quite up to that.
You don't need a dyno.

 

Is that before or after you put the quarter in it. [img]i/expressions/face-icon-small-tongue.gif[/img]

 

tug o war against a horse... OMG Yeah I am sure you and your bro can take one... right, maybe if your pulling from the front on his bridel....

Anyway Human horsepower is 1/6.

The power in watts is equal to the generator output voltage multiplied by the output current in amperes. Pedal or hand cranking power can be measured by connecting a voltmeter and ammeter into the generator circuit, and by multiplying the readings together. For instance, if the voltmeter reads 12.5 and the ammeter reads 10 amperes, the power being generated is 125 watts. To convert watts into horsepower, divide the number of watts by 746. In this example, 125 watts would be equal to 125/746=0.17 (1/6) horsepower.

 

WTF??? since when do you feed a horse quarters??? are you trying to make it choke or die somehow??

and in reply to west350bruin, of course im not gonna try to outpull one of those giants. Why do ppl own them anyways? you can't ride them, and even a lawn tractor can do anything a horse can

but you guys miss the point, i want to know what happens when you run on a dyno, or if it is even possible. you say that there is a formula for figuring out horsepower, but doesnt always make sense when you see the actual numbers on paper. Communism looks good on paper too, but wait till you try to put it to work....... IT JUST WONT!

well have fun

 

When i was in decent shape i could maintain 250 watts all day long (0.34 hp) with sprinting power upwards of 750 watts (1hp)
and BTW 250 watts will run you close to 30mph on flat ground with good form on a good bike.

 

I have a Dyno for Bicycles. it will measure output of up to 1500 watts. wich. I don't have that much power so i don't need to worry about it. wich thinkin of it all.. I need to start training again and stop being a lazy old man [img]i/expressions/face-icon-small-blush.gif[/img]

 

Yeah but a bike is giving you a mechanical advantage with gearing though right? Doesnt that change the end result or no?

 

Here is a dynochart of a dude thats pretty good.

 

Power is power. you only gain Torque thru the gears.
