Find the critical speed when the trailer is traveling over


The springs of an automobile trailer are compressed 10.16 cm under its weight.

Find the critical speed when the trailer is traveling over a road with a profile approximated by a sine wave of amplitude 7.62 cm and wavelength of 14.63 m.

What will be the amplitude of vibration at 64.4 km/h? (Neglect damping.)
