you had better find some way of using this in FS2 if you're gonna do all that work.

Jesus. Inertia... If I recall my 8th grade science class correctly, that's the forward motion of objects after the force pushing them is gone, right? Or something to that effect? That needs to be in FS...

this is about rotation, it's basicly how hard it is to change an objects rotation.

I am assuming then that the original settings even for the [v] ships were off. considering Baseball Bat effect, and the Judo Freighters, or is it something else causing that?

This won't get used by FS2, ever.  It would go in to a converter or a tool of some kind, since the MOI is stored in the POF file (precisely because loading 9 floats is more efficient than doing all of that math).  However, it's good to finally have some clue where the values are coming from.

@Flipside: maybe, but probably not.  MOI is really only used when a ship gets hit by weapons fire, which is why an improper one will cause your ship or a capship to go spinning wildly after only being hit by a stray shot.

Hey Bob, while doing this, have you given any thought to the problem of MOI in FS2 when you have 2 (or more now) ships docked together of widely different MOI and mass?  You know, dock an Isis to a Typhon, load yourself out with kinetic weaponry, fire on Isis and watch the Typhon spin like a propeller.  Can you overcome this?

Fun fact of the night: every USN ship has an overall density less than that of water.

well, hmm if i remember correctly inertia is not how long the object will move to his stop its acctually the object that trys to keep his previous stage(for example : moving in 3m/s or resting) what do slow him down: is the static\kentic powers and also the normal and the W(M*G) powers. but i probably wrong .

Moment of inertia is an object's resistance to change in rotation.

sort of, to actualy be more acurate it relates an objects rotational momentum with it's rotational velocity, you tell it what the current rotational momentum is and it'll tell you what it should be. this is how tops woble.

can you like write a caluculator that lets us imput ship dimentions amnd mass and other variables and have it output the proper moi values for us? you see, i am a moron. i can make ships look pretty, but i havent a clue how to make them spin properly.

also is there a way you can fakie newtonian physics by tweakinm moi?

no, dimentions are meaningless, shape is what counts.
