Hp Per Lb~!!

[nlzmo400r]

how do u figure out hp per lb ratings on cars, thanx in advance

[lessthanjakejohn]

You take the horsepower and you divide it by the weightt (pounds)

[nlzmo400r]

thats what i thought too, but that just gives u lb per hp, i need HP PER POUND, thanx tho

[redrocket]

hp is how much you can pull a 1000 meters in a minute

1hp=33lbs

[nlzmo400r]

ooooooooo, WHAT????!!!

[redrocket]

if you can pull 33lb a 1000 meter in 1 minute that is 1 hp

[nlzmo400r]

im not too sure i understand u, my car weights 3,o88 lbs, and i dunno how quick itll take to pull it 1000meters, or how much weight, im so confused!!, i know my car can cover a 1ooo meters in under one minute, but i just dont understand what the hell ur sayin dude

[lessthanjakejohn]

he is talking about something else....

he is talking about work*distance=power

but in math "per" means to "divide by"if you want it lb per hp, then do it like that

[nlzmo400r]

yea i thought so, but again, i know how to get lb per hp, but i want hp per pound, is hte way redrocket showed me the only way to do it??

[DAEDALUS]

Take the inverse (divide into 1). hp/lb = 1/(lb/hp) The assumption is that you're talking about comparing a car's output to its weight.

[nlzmo400r]

well i did that and i think my car gets like .o567 hp per pound, i thiought that was kinda off, seemed a lil low to me, i was figuring more like 2hp per pound, but then agian, 2hp multiplied by the weight of my car would give me 6k hp!!

You mean you don't have 6000 HP? Dude, your car sucks....it's slow.

[EZcheese15]

hp is how much you can pull a 1000 meters in a minute

1hp=33lbs

Not technically, because HP is a unit of Work, and lbs is a unit of force. So you meant to say:

1hp=33 lbs-meters LOL

Wow, imagine if all math was in engletric units.

[DAEDALUS]

Hmm...I got 1hp = 550 lbf*ft/sec = 10060 lbf*m/minute ...(work / time)

[EZcheese15]

Oh yeah, and work is measured in ft-lbs, not lb-ft. Torque is measured in lb-ft. Just to confuse you some more

[nlzmo400r]

hey appreciate it, now i dont know what the s*** im doin!!, o well, ill just settle for lb per hp, thanx for tryin tho guys, hey, i didnt notice this 'quick reply box' was named after fred, hmmm, congrats fred

Yeah, we put that up there so that you can reply specifically to Fred's Nazi-posts even faster.

[nlzmo400r]

it was just funny that i NEVER noticed that before, i assume that palmerwmd fred right?, did he start this site or something??

[yashin]

i'm not sure if i know exactly how to do this but if i remember my high school physics correctly ( which i don't) i beleive you use the cosine but that's my answer to pretty much any math or physics problem, everythign always comes back to the cosine

No, he was just the one who wanted to have a quick reply box.

I don't like to brag, but actually *I* was the one who started the modern-day site. Look at my join date if you don't believe me

The actual site was started by Rex, who is still the site owner (aka speeddoctor). But about this time last year, we completely redid the entire website and forums. We use to run on UBB forums that, to put bluntly, sucked. Our population since the change has atleast quadroupled, if not more.

Um yeah....the cosine doesn't really apply here.

Unless ofcourse you have offset vector forces applying different forces. Then you have to calculate the vector compenent forces using cosine and sine. But actually, you'd probably be using tangent also, and maybe ever the secant, cosecant, and cotangent, but only if you know your law of sines, and law of cosines.

yea, thats about what i figured

[Cold_Zero]

Nizmo,Did we get this resolved for you? I am not sure I understand your question. Are you trying to figure out the amount of work that is produced by your car for each pound it weighs? Or are you trying to figure out something else?

[nlzmo400r]

i was just trying to figure out how many HP i have for every POUND of my car, thats it, unfortuantely i only know how to get a LB PER HP , not HP PER POUND

[DAEDALUS]

Take the inverse (divide into 1). hp/lb = 1/(lb/hp) The assumption is that you're talking about comparing a car's output to its weight.

So...if you calculated .0567 hp/lb, then you have 1/.0567=17.64 lbs/hp.

im an idiot, thanx man,that sounds rite, appreciate it
