Re: Torque vs. Horsepower, who gets it?

When I win this does that mean I'm gona get a promotion
Maybe I won't be a cadet any longer

Sure feels like iv worked too long to be just a cadet

Re: Torque vs. Horsepower, who gets it?

If you read the above posted link
Its on force and states that it causes acceleration change of shape and motion change of motion
This should settle the argument
Because force if torque
Will post meaning of the others

Re: Torque vs. Horsepower, who gets it?

Newton's laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries,[2] and can be summarized as follows:
First law: The velocity of a body remains constant unless the body is acted upon by an external force.[3][4][5]
Second law: The acceleration a of a body is parallel and directly proportional to the net force F and inversely proportional to the mass m, i.e., F*=*ma.
Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear.

Qc please read newtons second law out loud
I will be standing by for my promotion

Woooooohooooooo
I'm a seamen apprentice

Re: Torque vs. Horsepower, who gets it?

Post padding party, woo hoo!

So tell me, is it possible for a motor with less torque to move something faster than another motor with a bigger torque number?

Re: Torque vs. Horsepower, who gets it?

He's actually soooooo close :facepalm:

Re: Torque vs. Horsepower, who gets it?

Yes it is
If you had the same boats motor ect weight ect
If the eng with the lower torque made that torque in a much higher rpm range
You could change the prop pitch or gear ratio and have a much higher speed
But you have to relize the the final output would have higher torque

Re: Torque vs. Horsepower, who gets it?

No the "final output" would have higher horsepower . . .

Since you keep posting reference information, I think you need to stare at the most important one: torque x RPM / 5252 = horsepower.

Re: Torque vs. Horsepower, who gets it?

Look fellas
There a lot of things I don't understand but this is what iv done for a living for a long time
And I do a lot of studying
I think this biggest confusion come form the drag strip
At the strip if you have the same torque with a larger hp rateing your quicker
Well people think of that as faster
Like said faster and quicker are a lot different and what I do for a living I have to understand that and not kinda but fully understand or the motors I build won't be winning races
For you to have a motor with the same torque but a higher hp rateing you have to make that torque in a higher rpm range
I learned along time ago that I wasn't building horse power rather I was building torque in a higher rpm range to make more horse power


Now can I get some info on wood finishing
This is a subject I know almost nothing about

Re: Torque vs. Horsepower, who gets it?

Everything in that post is correct ^^^^^

 

[g1sammons]

Re: Torque vs. Horsepower, who gets it?

Qc
You have to understand that horsepower is rated off what torque and do in a amount of time
Horse power is not a measure of force
And if you have a gear reduction your horse power rating goes down and your torque goes up

 

[g1sammons]

Re: Torque vs. Horsepower, who gets it?

Let me say it like this if you final output has a highr rpm than your eng it would have a higher hp rateing but your boat would be slower
You can argue with me tell me I'm wrong all day but newton
Well he's out of legue and he says it's force that's accelerates
Horse power you have to understand is a measure of work done over a distance for a cretin amount of time
It simply is not a force

Re: Torque vs. Horsepower, who gets it?

And if you have a gear reduction your horse power rating goes down and your torque goes up

And that is false except for the fact that higher gear reductions introduce higher parasitic losses. Here's the math (minus the parasitic losses).

100 lb ft @ 5000 RPM = 95.2 hp

100 lb ft @ 5000 RPM into a 2:1 gear reduction becomes 200 lb ft. @ 2500 RPM = 95.2 hp

100 lb ft @ 5000 RPM into a 3:1 gear reduction becomes 300 lb ft @ 1666.7 RPM = 95.2 hp

Works with overdrive too.

100 lb ft @ 5000 RPM into a 1:1.5 OD becomes 66.7 lb ft. @ 7500 RPM = 95.2 hp

Edit: I have never, not once, said that horsepower is a force. You keep mentioning time without making the connection that force applied within a specific time make power. You can't even calculate speed without time and this is where your words (maybe not your understanding) fall apart.

Re: Torque vs. Horsepower, who gets it?

Higher horse power means you get things done faster in time
Not faster in speed

Anybody that wants to tackle that one ^^^ go ahead. I'm done. Mr. Sammons wins the I don't get it award . . . Holy flip.

 

[g1sammons]

Re: Torque vs. Horsepower, who gets it?

You got me there your right the horse power rating would be the same
I was incorrect about that

 

[g1sammons]

Re: Torque vs. Horsepower, who gets it?

Now what about that wood finishing info

Re: Torque vs. Horsepower, who gets it?

I'm getting another Mod to close this, I can't take it. I apologize to everyone who stumbles across it . . . I thought I could manage what has become worse than an oil thread. What an arrogant idiot. Oh, oh, I meant me . . . I can't ban the guy for arguing with me, I can't delete his posts from my own thread, that would suck. I am as dead here as Herman Cain. There I brought up politics; that should do it
