Polar Moment of Inertia Calculation

In the top list box you enter the items on your race car including their weight and position within the car. In this example, only two items have been entered.

When entering data, you can start with the biggest, heaviest parts and continue entering smaller, lighter parts. This way you can get a reasonable calculation quickly.

This gives you a calculated CG height and position which can be compared with the one calculated in the chassis weights calculation and/or the suspension weights calculation. Also provided are a polar moment of inertia calculation and statistical analysis of the items in the list. This is useful for comparison purposes: How much would your polar moment of inertia be reduced if you moved a component a certain distance closer to or farther from the vehicle center line? How much would your center of gravity height be affected if you raised or lowered a certain component?
