How would I calculate how much stress a part is enduring?

[ensou04]

Im trying to figure out what forces are in play that causes parts to break and bend in code format.

I have Isolated each parts already, I know how to grab the BreakingForce and Torque limits but I cant figure out what I need to get the amount of stress there is for specific part

The plan is to add soundeffects for each part that is being stressed so you can "hear" which part is having it worst. And at very high stresses where parts will actually break, I would play a sound that would correspond to the situation.

This is for the mod Im working on in This Thread

foreach (Part part in vessel.parts) {
    if(part.physicalSignificance == Part.PhysicalSignificance.FULL)
    {
         //whattodohere
    }
}

You can't get the current stress applied to a joint and you can't know the acceleration applied to each part, so I don't really see how you can get the stress

Yeah thats what I found out, because most members inside the Part class are constants and some are just universal like the angular velocity and drag.

So there is really no way? how does the game handle joint breaks though?

The game define Unity Joint and set their breaking force and torque. They are handled by the Unity physic engine and you don't get to see the internal values (AFAIK).

You can get the Joint class used by searching the part gameobject component (The Kerbal Joint Reinforcement mod code can show you how to do that) but you can only set limits there. The game when a joint break with the OnJointBreak message, that provides the break force.

You're right, theres no way to know the internal values. and alot of stuff is hidden within KSP itself. I guess there really isnt anyway to know the acceleration per part.

Thank you for explaining it to me

My last resort actually is just use FAR, I think somewhere inside FAR is a code that breaks joints and I Guess I could do something about it to do what I want to achieve

I'm curious about this as well. I build some large structures and if I have a lot of repeating parts it is difficult to know which parts have broken from the F3 event list, (for example dropping submarine crafts onto the water surface can be an exercise in frustration).

Perhaps if you can't display which parts are getting stressed maybe an add on could be created that pauses the game when one joint breaks and highlights the affected parts in colour? That would be a God send.
