Thread: Mechanics in motion

Tweet

Hi group. Requesting a little help here on mechanics in motion. I'll try to spell this out in words as best I can. If I were to use a a screen door closer (this is just theory so don't worry about safety yet) as a pneumatic ram and the length of the shaft was say 10 inches I would get 10 inches of distance for movement and say 5 pounds of lifting power (remember just theory here).

I know there are ways to use things like scissor lifts to change the distance an object would move or increase the power available for lifting.

My question is where are the www links or "how tos" on this data?

I'd like to do things right (read safely) but every pneumatic ram or cylinder I've found is very expensive once you go much further than a few inches. So I would like to be able to use a smaller device with an amplification method to get more distance and or power.

PS Yes I've read the excellent pneumatic data on this forum and it is VERY helpful on setting things up.

Thanks to all for looking at my question,

Hi Sparky....you might have to post your question in the general area for a response....this area is for the online prop building groups projects, mostly instructor & student threads only here.
