And It Makes the Cow Mad
Apparently...cow tipping? Pretty much a myth (which, if you've ever paid much attention to cows, would probably be a given):
A cow of 1.45 metres in height pushed at an angle of 23.4 degrees relative to the ground would require 2,910 Newtons of force, equivalent to 4.43 people, she wrote.
Dr Lillie, Ms Boechler’s supervisor, revised the calculations so that two people could exert the required amount of force to tip a static cow, but only if it did not react.
“The static physics of the issue say . . . two people might be able to tip a cow,” she said. “But the cow would have to be tipped quickly — the cow’s centre of mass would have to be pushed over its hoof before the cow could react.”
