Describe the bug

The attached .ork file is the Simple Model Rocket example, modified so the nose cone's thickness is set to 0, and its shoulder's thickness is also set to 0. When it is simulated, the result is a stack dump due to a NaN in the calculation of the longitudinal moment of inertia.

This is a regression from 23.09; 23.09 was able to handle it.

To Reproduce

1. Load the .ork
2. Run a sim
