Descreiption of Relationship between Angular and Linear Speeds
The stepped shaft is secured to a main shaft, which itself is secured within a bracket. The bracket can be bench or wall mounted.
Wrapped around the circumference of each step of the shaft is cord. At the ends of each cord is a single adjustable bob. The adjustment of the bobs can be made to ensure that the starting positions of each bob is the same even though the steps are different diameters. Alternatively the starting position of each bob can be made different.
