Pendulum ride - Wikipedia

Pendulum rides are amusement rides based on the motion of a fixed pendulum. [2] The configuration of the ride consists of a gondola, arm, and an axle. One end of the arm is fitted with a passenger-carrying gondola, while the other is attached to the axle. In some models, the arm extends beyond the axle and is fitted with a heavy counterweight.
