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 mass. The adjustment of the mass can be made to ensure that the starting positions of each mass is the same even though the steps are different diameters. Alternatively the starting position of each mass can be made different.
The shaft is rotated by a handle which can be locked by a retaining screw. The angular movement of the shaft and the corresponding linear movement of the weights can be compared.
