Sketching Sine

The Sketching Sine mechanism is designed to help students to understand how the unitary circle works, in this mechanism they can easy appreciate the variables (frequency, amplitude and phase angle) which the sine waveform is consisting of and how they can manipulate them to sketch diverse outputs, this model is based on the cam mechanism which also transform the model in a good example to understand the dynamics of this mechanism for engineer students , we provided a basic set of gears but the model is customizable just change the ratio of the train gear and you will have changed the frequency of the Sine.
