1. The rotating parts of a front wheel assembly of a car have a total mass of 35 kg and aremeasured to be out of balance. The unbalance can be corrected by attaching a 150 g weightto the 375 mm diameter wheel rim. The tire has a diameter of 700 mm. The car springs havea modulus of 50 N/mm and the tire has a modulus of 600 N/mm for small de ection. If thecorrection is not made, at what car speed will resonant vibration of the wheel occur
