Discussion Overview

The discussion revolves around the feasibility of constructing a pendulum clock that operates independently of gravitational acceleration and temperature-induced changes in pendulum length. Participants explore theoretical possibilities and practical limitations related to the design of such a clock.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether it is possible to create a pendulum clock whose period is unaffected by variations in gravitational acceleration and temperature changes that affect pendulum length.
  • Another participant asserts that the period of a pendulum is fundamentally dependent on gravity and pendulum length, suggesting that a clock relying on a pendulum cannot function under varying conditions.
  • There is a suggestion to consider alternative clock mechanisms that are not influenced by gravity or temperature, implying that a pendulum may not be the best choice for such a design.
  • A participant references historical clocks designed in the 1700s, indicating a potential area of exploration for overcoming the challenges posed by gravity and thermal changes.
  • There is a request for clarification on whether the aim is to find a solution to the dependency on gravitational acceleration or thermal changes affecting the pendulum's period.

Areas of Agreement / Disagreement

Participants express differing views on the viability of a pendulum clock functioning independently of gravity and temperature. There is no consensus on whether such a clock can be designed, and the discussion remains unresolved.

Contextual Notes

Participants have not fully explored the implications of their assumptions regarding the physical principles governing pendulum motion, nor have they provided detailed mathematical analyses of the proposed concepts.

Hey
I asked myself whether there are any possibilities to construct a pendulum clock, which period is independent of the acceleration of gravity, which may differ at different places, or the extension of the pendulum lenght, that is caused by different temperatures?
 
Engineering news on Phys.org
And? What answer did you give yourself?
 
well I have not a clue..that is why I want to ask you...
 
Well, the force of gravity and the length of the arm are pretty much the things that define the period of a pendulum, so if you are were hoping to build a clock without those things being constant, it pretty much couldn't use a pendulum.

Since those are things that a pendulum has as its weaknesses, why would you use a pendulum at all, instead of using an alternate method that is not susceptible to the very things that you plan to vary?

Have you looked into the clocks designed in the mid to late 1700's by http://www.nmm.ac.uk/harrison" ?

Hi-
but the point is: do you want to have an idea on how to overcome to acc. gravity or thermal change on the value square_root(g/L) or what?
