Main Question or Discussion Point

why there is a negative sign in the tensor moment of inertia??

 

[OldEngr63]

Usually, there are six negative signs. Did you have a particular one in mind?

 

[taba94]

no,my question is that why there should be a negative sign in the tensor moment of inertia?

 

[Vanadium 50]

As it was pointed out, there are several negative signs. Which one are you talking about?

 

[taba94]

all of them

 

[jerromyjon]

Are you asking what it represents or in what conditions that you use it? I don't know why it is there either, just trying to help clarify the question.

This question does not make a lot of sense. A better question would be: why is the moment of inertia tensor defined the way it is defined?
