GS-301 Wheel & Axle


SKU: GS-301 Category:


This design of the traditional wheel and axle eliminates the usual cumbersome fork and pointed pivot bearings and replaces them with a simple axle and single bearing.

The Wheel and Axle is used to show the relationship and significance of various pulley diameters when used in a mechanical system. The GS-301 consists of a molded wheel with four individual pulleys of different diameters. The ratios of these diameters is a sequence of approximately 3, 2, 1.5, and 1

The GS-301 has four pulley steps, each with a small hole drilled in each rim for attaching a string. The stainless steel axle is mounted in a ball bearing that is embedded in the center of the molding.

Diameter: 10 cm

Tripod, clamp and post are shown for demonstration purposes only and are not included.
