Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

i have a small idea in my small brain that i can not shake off, it involves converting a vertical rotating motion to linear up and down motion

i know it is possible but how? and it has to be mechanical only no funny gadjets only things that i can find easly.
any ideas??
thanks

I am sure these things can be done mechanically, but why?
Any mechanical transfer of energy is a loss. Gearing produces energy loss in the form of noise, and friction.

Vertical mills produce a lot of grunt but cannot get the high speeds required of some motors to perform.
Horizontal mills can produce faster Rpms, but are harder to start.

I don' understand why this is important, but I understand that a fresh iea is always good to hear.

i am trying to use the levrage that a pry bar produces.
we all know the longer the bar the easier to pry somthing because it takes less energy due to the legnth of the bar and levrage.

i dont know the proper term for this sience but i am trying to use it in my vawt, If it is possiblea and that is my aim.

thanks

Sorry, but no.
Less force X more distance = Same Energy

Brush up on that science before designing things. To many of us the learning process, no matter what background we have, makes the whole project worthwhile. But ignoring basic physics can make a project downright frustrating.

ok, but can you please explain a bit more.
i dont understand the "Less force X more distance = Same Energy"

i am willing to learn and accept.

thanks

There seems to be some confusion here with force, energy, and power.
