a) Fig. 2 shows a rim of a tractor tyre of diameter 60 cm and width 25 cm. After
inspection, the tyre was found imbalanced. It seems to the equivalent a 2 kg mass
5 cm from the outside of the tyre and 30cm from the centre of the tyre at 100°, and
another one 1 kg mass at 18 cm from outside of the tyre and 10 cm from centre of
the tyre at 300° angle. Find masses that should be added to make it balanced at the
outside and inside tyre at the rim (30cm from the centre)
