7. Washboard roads

When an unpaved road (usually sand or gravel) is used by many cars, a wavy pattern is formed causing strong discomfort for the drivers. Study how the wave parameters depend on the properties of the granular material and on the average speed of the cars. Is there a safe way to drive fast on this type of road? https://practicalmotoring.com.au/4×4/how-are-corrugations-formed/
