You will see "type:car" is automatically specified. This feature automatically sets the moments-of-inertia based on overall mass, wheelbase, and geometrical size for vehicles [1 - 4]; that is:
where m is the vehicle mass in kg, WB is the wheelbase in meters, and L is the overall length in meters.
Note, for type:truck, only the mass and geometrical size are used (note, type:truck is generally used for heavy (commercial) type vehicles. SUVs and pick up trucks are typically assigned type:car by default). So for type:truck, we have by default (based on the prism method) :
where m is the vehicle mass in kg, W is the overall width, and L is the overall length.
To use your own values, simply press the "type" button and select "user."
You should now see accessible fields in which to enter your own values for Ixx, Iyy, and Izz.
