- The idea of "shaking" may seem like something fun to laugh at for people, but for many animals it is a means of survival, and the need to stay dry.
- Animals, such as dogs, shake at frequencies as high as 27 Hz for smaller animals
- 4 Hz for larger animals
- The calculation for the oscillation is R0.75,
- When the radius is larger, a greater force is exerted
- A greater force can be exerted on the fur when the radius is larger
- the skin moves at the same frequency as the body, but (especially with very furry animals) when the skin is looser, it will movefaster than the body, therefore it has a greater force and can remove water faster
- Another factor affecting how quickly water can be removed is the type of fur: Some fur retains a lot of water, while others are densely packed on purpose, not allowing water to penetrate through it to the skin
