In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism ...

The inverted pendulum is controlled in this article by using the nonlinear control theory. From classical analytical mechanics, its substructure equation of motion is derived. Because of the inclusion ...

I am going to make a prediction. As people start to get bored with their fidget spinners, they are going to start playing with these double pendulum fidget spinners. The normal spinner has a bearing ...
