【Abstract】 A self-made three-wire pendulum was set up,and the cooked degree of eggs was studied.It was found that the swing period of the raw eggs tended to damp rapidly.The cooked degree of eggs could be sensitively judged by the number of period of steady swing.The damping resulted from the moment of resistance that came from the friction of the egg white and yolk with the egg shell.更多还原
