    Total Work out of Three Bodies (Thermodynamics)

    The problem is: Having three bodies with thermal capacities (C) as sources of heat to a heat machine, what is the maximum work I can extract from this system, given that the bodies are at temperatures T3, T2 and T1 (T3>T2>T1), leaving them at an equal final temperature? I tackled this...

    Lagrangian of three bodies, using an exponential potential

    What I know: L = T - V V = e^(x1-x2) + e^(x2-x3) for n = 3 and a mass = 1 What I believe: T = .5Ʃ (x'_i)^2 from 1 to n So let's say you have three bodys that can just be considered pints masses of 1 and on the same line: x1 x2 x3 They have an...

    Test of GR's increase of inertia near bodies?

    According to GR, the inertia of bodies is greater near masses. - https://en.wikisource.org/wiki/Geometry_and_Experience Has this been tested? I did not find a clear answer, the gravity tests seem to be testing other things. Can it be tested? Intuitively I think that it should be possible...

    Does required time for free falling bodies is independent of mass?

    In a class at OCW 8.01 Professor Walter Lewin said... "...there are very prestigious physicists who even nowadays do very fancy experiments and they try to demonstrate that the time for an apple to fall does depend on its mass even though it probably is only very small, if it's true but they...
