Is there a mechanical way of increasing angular movement?

Click For Summary

Discussion Overview

The discussion revolves around the mechanical methods to achieve a greater angular movement of one component (C) compared to another (B) while both are connected to a common pivot point (A). The scope includes theoretical and practical mechanical engineering concepts.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests increasing the centripetal acceleration at point C to achieve a higher angular velocity, but expresses uncertainty about this approach.
  • Another participant proposes using an epicyclic gear system, describing the roles of sun gear (A), planet gear (B), and annular ring gear (C).
  • A different participant describes the scenario as a simple gear joint and provides a relation between the distances to maintain the desired angular movement ratio.
  • One participant seeks clarification on mechanical methods, mentioning the possibility of a "cam-type" linkage or a secondary pivot point to achieve the desired motion.

Areas of Agreement / Disagreement

Participants present multiple competing views on how to mechanically achieve the desired angular movement, and the discussion remains unresolved with no consensus reached.

Contextual Notes

Participants have not fully explored the assumptions behind their suggestions, and there may be unresolved mathematical relationships or dependencies on specific mechanical definitions.

(A) being a common pivot point for (B) and (C). In relationship to (A), I would like to have (C) move twice the DEGREE OF ANGULAR movement as (B).

Any suggestions or thoughts on how I might accomplish this would be GREATLY APPRECIATED!

I believe that if you increase the centripetal acceleration at point C then it will move at a higher angular velocity.
someone please correct me if I'm wrong.
 
How about an epicyclic gear system? A is the centre of the sun gear, B is the centre of a planet gear, and C a point on an annular ring gear running on the planets?
 
You just described a simple gear joint. Just keep the relation DAC = 2DAB
 
Thanks for the suggestions. While I understand the concept, I'm looking for a mechanical method of rotating (C) twice that of (B) when both are connected to (A). Wondering if I need to consider some sort of a "cam-type" linkage or, possibly, a mechanical link to a secondary pivot point?

Thanks again..
