Teaching aid for teaching the principles of an impulse driver
First Claim
1. An educational tool for teaching principles of angular momentum, torque and linear force, comprising:
- a frame comprising an upper platform and a lower platform,an upper motor disposed on said upper platform,a lower motor disposed on said lower platform,a spindle assembly comprising a shaft comprising an upper end and a lower end, said upper end of said shaft being connected to an upper coupling and said lower end of said shaft being connected to a lower coupling,a turntable comprising a mounting pin extending from a top surface thereof, the mounting pin being disposed in a offset position relative to a center axis of said turntable,said lower coupling being connected to said turntable via said mounting pin,said shaft comprising an axle hole disposed along a length thereof,an axle positioned through said axle hole of said shaft, wherein said axle is freely rotatable about a longitudinal axis of rotation within said axle hole,a weight assembly fixedly attached to said axle, wherein said weight assembly is rotatable with said axle about said longitudinal axis of rotation, wherein said longitudinal axis of rotation is offset from the center of mass of said weight assembly, andwherein said upper motor is structured to drivingly rotate said upper coupling about an upper axis, and wherein said lower motor is structured to drivingly rotate said turntable about a lower axis.

Abstract
An educational tool for teaching principles of parametric resonance, linear force and angular momentum is presented herein. The tool includes a frame having a spindle assembly with a shaft. The upper end of the shaft is connected to an upper coupling and the lower end of the shaft is connected to a lower coupling. A turntable is positioned below the shaft and includes an offset mounting pin extending from a top surface thereof. Furthermore, a weight assembly is positioned through a hole in the shaft via an axle, wherein the axle is rotatable about a longitudinal axis of rotation within the axle hole of the shaft. The upper motor will rotate the shaft in one direction, while the lower motor rotates the turntable in a second, opposite direction causing the weight assembly to rotate and oscillate about the longitudinal axis with a varying moment of inertia.
