I already explained why it's wrong.Unfortunately, you were too busy telling me how clever you are, and how little I understand , to actually understand it.Have another go.https://en.wikipedia.org/wiki/Dimensional_analysisQuote from: Thebox on 20/04/2019 13:25:27I'd demonstrate it to you in person ever so easily . Do it by video.

What does U represent? What does F represent? What does X represent? What does t represent? I ask because you make none of this clear. What are the units of each variable? What dimensional analysis did you use to arrive at these units?
How can I explain it to you without giving it away totally ?
QuoteHow can I explain it to you without giving it away totally ?It makes no sense to try to talk about an idea if you aren't even willing to explain it well enough that other people can understand it. If I say, "Yu politu rety lo reon" and people don't know what I'm talking about while I'm unwilling to explain it, what have I accomplished?
Why the cube of force? What on earth does that even mean? Force is a vector. The square of a vector is a scalar, a single number. Multiplying the vector again by a scalar in this situation is meaningless. You would be better off learning about tensors. The inertia tensor would be your best place to start. Try applying some thought. Then maybe you might start having productive conversations.
Isotropic means the force is the same in all directions. Cubing it doesn't show that. You are cubing the force in only one particular direction. There are 3 orthogonal axes. These are x, y and z. You could call them x1, x2 and x3 respectively. Your vectors then consist of the three values [x1 x2 x3]. You then need to know how to manipulate the values to get a meaningful result.

I think I could just say If U is energy then multiplying it with force makes no sense either. Force times distance equals work done equals energy. However, force is a vector quantity so it isn't quite so simple.

Place U in an isotropic vice and turn the vice handle UF³ The force is centripetal and isotropic , the will decrease in volume but become more dense . MF³

I trust you Mr C , want me to PM them you ?
(BTW, it's right, so you will need to fix the problem)
What problem ?

OK, so, as usual, you are wrong by dimensional analysis.Nobody is going to invest in something which a bright schoolkid could show to be wrong.But that won't stop you getting a patent.
