It Just Keeps Going…& Going…& Going…

Ideal for home or classroom demonstrations, this high-quality gyroscope with adjustable bearings and near perfect balance will keep spinning for minutes when optimally positioned. Includes plastic gimbals, rocker, pivoting housing and instructions. Measures 7.5 x 4.5 x 4.5.

Background:

A gyroscope is a device that consists of a spinning mass, usually a heavy disk called a rotor, that is mounted on a base. The rotor has a spin axis positioned through the center of it. The rotor is mounted and moves within gimbals that allow it to move freely in any direction. This is mounted within a frame. Because of its ability to move in any direction, the rotor maintains its orientation, regardless of any movement in the base. (Orientation refers to an object being positioned in such a way that one point on the object is fixed.)



Picture this: you’re on a boat. The boat has waves coming at it from two sides and is moving up and down, side to side and forwards. You happen to have a gyroscope on the boat. Despite the fact that the base will move with the boat, the rotor will always remain level.

Product description

An educational standard, this balance features a durable one-piece base, moded of high impact styrene with three-point suspension for slf-leveling. The beam is aluminum for lightweight sensitivity and pivots from self-aligning genuine agate bearings. For accuracy, it is die stamped so that precisely equal distances are maintained between pivot points. Two injection moded sliding weights provide for fine adjustment. With a load of 50 grams per pan, the balance has an ultimate sensivity of 10 mg. gram mass set standard masses ranging from 100mg to 50 grams, packaged in plastic box with tweezers. One weight set required for each balance. For grades 7 to 9 and ages 12 to 15 years.
