In Figure.4, a car wheel balancer device is used to estimate the location/direction and mass value needed to be attached to the wheel in order to statically balance it and prevent vibration during driving. Your role is to calibrate the system measurement by constructing theoretical calculation of a sample wheel and compare it with the results of the computer. The unbalanced wheel can be modelled as in Figure.5 and the four distributed point-mass as in Table.2.
