geepers surely someone has had their car on a swing or at least predicted the moments in a spreadsheet from cad modelling or from the model itself.

hung the car from four slings, gave it a rotary oscillation, timed the period of oscillation, and using the equation in Claude Rouelles course notes calculated the inertia. We tested it out on simple objects first, and the theory holds up pretty well, the limitation is timing it.
