The system is for studying the acceleration of a gear system under different gear ratios.

The system consists four parallel shafts with fixed and sliding gears and supported by self aligned ball bearings on a base frame.  Each pair of adjacent shafts has two transmission ratio, providing 8 different gear ratios between the first and the last shaft. Inertia mass with torque drum is attached to each shaft. A chord wound around a drum and the weight hanger provides a means of applying a torque. The gear system is attached to a wall supported on two legs for weight hanger travel. By timing the fall of the weight hanger, the acceleration of the system can be calculated. A sprocket and lock pin, and a winding handle are provided for raising the weights. All gears are enclosed in a casing with a transparent cover for safety.
