A wheel-and-tire assembly is being tested on a tire balancer. The wheel-and-tire assembly is slightly out of balance. If this wheel were on a car, the car could be very difficult to control.
What is known:
- slider mass m1 = 20 kg
- wheel and tire mass m2 = 25 kg
- spring constant k = 7,000 N/m
- damping constant c = 56 N s/m
- eccentricity d = 1 cm
- rotation speeds 90, 120, 150 rpm
