How does gravity affect the balance of an egg and muscle strength?

AI Thread Summary
The discussion clarifies that an egg can stand upright due to its shape and the presence of an air sac, rather than the effects of gravity. Users explain that with proper balancing techniques, an egg can be made to stand almost anywhere. The ideomotor effect is mentioned as a related concept, but the overall consensus is that the claims made in the referenced video are misleading. Additionally, the idea of being at "latitude 0" or the "center of the world" is dismissed as nonsensical. The conversation ultimately emphasizes that the egg standing trick has no real connection to gravity.

Referring to following video starting at 7:00 minutes, there are something related to gravity, I don't understand,

  • Why can egg stand up without falling?
  • Why do your muscles stronger in different locations?

Does anyone have any suggestions?
Thanks in advance for any suggestions

Edit, yet another crackpot link deleted.

1.If you take time to balance it, an egg can stand pretty much everywhere.

2.Look up ideomotor effect.

Bottom line is: nothing to do with gravity.
 
There is, at the "rounder" vertex of an egg, an air-sack. One common trick is to strike the egg sharply enough on the table to crack it slightly and flatten out that air sack (because it is an air sack, no egg leaks out) and let the egg stand on the flattened end.

As Bandersnatch said, this has nothing to do with "gravity". Pretty much everything said in that video is non-sense. I assume you know, of course, that just being at "lattitude 0" means you are on the equator and does NOT mean you are at the "center of the world". The equator goes all the way around the earth. Looks like a tourist trap to me.
 
That video is garbage. The center of the world? Seriously? The sink trick is nonsense, the egg trick is nonsense.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
