I don’t fully understand your diagram. It looks like you have superimposed three states in one picture: 1. Joint B is down to the left...

Bizarre. But you understand now that one should use - pounds mass for mass and pounds force for weight , - or kg for mass and Newtons...

I find your diagram illegible. If I expand it at all it becomes very fuzzy.

Please post your answer - maybe it is right. In case it isn't, it will save time if you also post your working.

As I showed in post #23, changing to mass actually made it more complicated because when formulated as a mass equivalence Archimedes...

Weight is mass times gravity. I still worry that your post #8, where you imply that going metric involves switching from weight to...

I definitely did not complain about your referring to mass instead of to weight. I merely pointed out that it is usually quoted in...

No, I am saying that mass and weight are different entities, but in the context of a fixed acceleration that applies to all the masses...

I don’t understand the connection between weight versus mass and the use of metric units. The two are independent. A weight is a force...

Archimedes' principle is usually expressed in terms of force and weight, not mass, but since the weight of the vessel and weight of the...

I would think it extremely unlikely.

I assume you mean to suggest they are infeasible sources of mechanical work. In scenarios 1 and 4, quite so: no work can be done. In...

I played with a simple one dimensional model. Scenario 1: Particles on a line have a uniform velocity distribution from ##-V## to...

Is it that clear cut? For a pair of contra-rotating discs there is a frame which minimises the KE but it is still substantial, and most...

Leaving aside that not all internal energy is thermal, I assume that is in response to inaccuracies you see in the OP's view, namely...
