Methods to convert linear movement to circular

Click For Summary

Discussion Overview

The discussion centers around methods to convert linear movement to circular movement, exploring various mechanisms and their efficiencies. Participants raise questions about the parameters and limitations of the topic, as well as the context of the inquiry.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants suggest using pistons and turbines as methods for conversion, while others challenge the accuracy of these claims.
  • One participant questions the vagueness of the original inquiry and asks for clarification on its context, such as whether it is a homework question.
  • There are humorous remarks about the nature of the discussion, with references to "crank threads."
  • Participants express frustration with the prevalence of marketing over scientific information online, suggesting that many answers can be found through simple searches.
  • One participant inquires about the efficiency of converting gas pressure into rotational energy, noting that the method may depend on the pressure available.
  • Another participant proposes that high pressure might favor turbine use, while low pressure could benefit from wide area piston engines.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the methods discussed, with some disagreement regarding the validity of using pistons for conversion and varying opinions on the most efficient mechanisms.

Contextual Notes

The discussion lacks clarity on specific definitions and parameters, and there are unresolved questions regarding the context of the inquiry and the efficiency of proposed methods.

Hello,

Obviously using a piston, you convert linear movement to circular.
Or using a turbine.

Other methods/mechanisms?
 
Engineering news on Phys.org
Pistons do not convert linear movement to rotational movement.

What are the parameters/limitations of this question? Is it homework? Have you googled it? This is very vague/open ended.
 
Is this one of those crank threads? :biggrin:
Two jokes for the price of one.

I did a Google search on your thread title (omitting "Methods to"), and got a bzillion hits. Maybe try that?

That's so often the answer to questions on PF.
Science is clearly not as well funded (on the internet) as marketing is. Once you are hooked into Amazon or eBay and you can't help finding the thing you want (or the thing they tell you that you want.
Just imagine this response from PF: "People who enquired about convert linear motion also found machines, inclined planes and levers of interest"

No kidding. Literally less than 30 minutes after I did some Google searching for typical images of Peltier generators with heaters, I got an advertisement in my other browsing for similar Peltier generator setups. Yoiks...

What is the heat source for your Peltier generator? What is the heat flux into the generator? What is the typical efficiency of the conversion to electrical energy? What power do you estimate you have to run the electric motor? Can you show us your calculations so far?

So what's the most efficient way to convert gas pressure into rotational energy?

I am sure that would depend on the available pressure. For high pressure you'd be talking in terms of a turbine but for low pressure, some wide area piston engine could be best (I'm thinking in terms of a domestic gas meter mechanism).
