Roshni-Writeup

 
 * 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 R 0.75  ,
 * 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 quick ly 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
