In an early post I basically said the average engineer didn't know what they were talking about. Of course thats not true. I should of said- just because someone says they're an engineer doesn't mean they're always right about engineering topics.
Then Belgian who claims to be an engineer makes this post below about HP & Torque and he agrees with Bob and Peter on their therories- and he calls me stupid!
I've read post by these three guys who claim to be engineers and physicist. What they say about the relationship between HP & Torque make me think they don't have their facts straight.
They keep talking like HP & Torque are two different things and not related - they're not. Read their post they say it takes Torque to get the saw up to max speed, but then when you start cutting its about raw HP. Seems like your saying when you start cutting "Torque" stops doing its job and "HP" takes over. That just doesn't make good "engineering" sense to say that. When your cutting wood, something has to pull the chain through the wood- "The Chainsaw Fairy" doesn't jump in and do it - the Torque output of the engine does the job. Its all about Torque! You can't talk about HP like its not related to Torque. Torque comes first then you calculate HP from that.
I think Peter said in another thread ...two saws that have the same cutting speed the one with higher HP will win - thats true. Look at the formula- if the speeds are the same then the higher HP as to have more TORQUE.
I admit I don't undersand it all 100%, but after reading these guys post, I don't think they do either.
