Square Wheels

In Square Wheels, an ten-inch square wheel rolls smoothly across a very bumpy surface. The bumps are carefully designed, flat catenary curves which exactly match the sides of the wheel in length. These curves also exactly compensate for the changing axle height of the square wheel as it rolls along. The axle of the wheel does not move up and down. Extensive graphics explain the exhibit.
