As centripetal force varies with distance from the centre of the creature, its radius is therefore crucial to work out the speed of the oscillations. The team arrived at an equation that calculates the frequency of that oscillation as R0.5.
To test that hypothesis, the team filmed a wide range of dogs shaking, and used the images to calculate the period of oscillation. For a labrador retriever, that turned out to be 4.3 Hz. He then expanded the search, filming animals as small as mice (27 Hz) and as large as bears (4 Hz).
So the bigger the animal, the slower it can shake to achieve comparable drying, but the relationship isn’t linear. Instead, it approaches a limit of 4 Hz as an animal grows in size.

Morning Ken I can't say I understood all you have written (And NO I am not Blond:O) But I did enjoy watching and learning some things I did not know ~ Ally x
ReplyDeleteI am with Ally... but I think that larger animals would shake more slowly because they generate more force and it take more energy for them to shake water off.
ReplyDeleteAnd dogs figured it out on their own without grants!
ReplyDeleteNow that was really interesting! Thanks for sharing!
