Where the Wild Things Are
Sadly, yes.Are we really debating how hp is calculated

Where is your point?
No, I mean that if the most basic of algebraic manipulations has befuddled you then there is no basis for discussion:
HP = Torque x rpm X 1/5252 is the same equation as Torque= HP x 5252/RPM
We certainly do

Have y'all ever wondered why all the guys that used to be here regularly left?
There are three variables. To solve for any one of them you must have the other two. Any of them could be measured directly, but it is usually easier to measure torque on most dynos. And rpm is simple to measure.In solving for torque how do you get your horsepower number?
CurrentThere are three variables. To solve for any one of them you must have the other two. Any of them could be measured directly, but it is usually easier to measure torque on most dynos. And rpm is simple to measure.
None of that changes what the terms represent in regard to physics. Power is the rate of doing work (transferring energy). Torque by itself does no work and neither does rpm.
This entire discussion is equivalent to asking "what is more important, voltage or current?", when in fact voltage x current = power and neither is more important.
No, torque is a measurable force. 1lb of force applied on a 1' lever = 1ft-lb. Horsepower is a calculation, torque (measured in ft-lbs) x rpm/5252= horsepower.
You have torque and horsepower in the wrong positions of your equation. They are not interchangeable.
I am partially wrong in this post and probably several more. I misread huskstihl's equation. I kept transposing rpm and 5252 in my brain and seeing it as torque=hp x rpm/5252.

You could drive a generator, run a known resistive load and measure the current. You could turn the mechanical energy into heat and measure the temperature rise of a known mass. There are plenty of ways to set up such an experiment/test.How do you measure horsepower directly?

It's easier to measure the force at a known distance and calculate torque.
They look like wieners. Everyone... "I have a potty mouth"Try extra banana's ,they work pretty good .They are those tunnels next to the intake in this 460 jug ,Look like banana's to me anyways ,and a monkey put them in there .

These saws have zero chain speed. There WAS chain speed to get them where they are.Chain speed is not going to help you with 880s and 50'' bars in very hard dry Redgum.
