A simulation of Tschebischeff's compound mechanism for tracing a straight line. The curve is generated by composing two other approximate straight line mechanisms that cancel each other''s deviations. This is an abstract model where the frame and supports have been removed, leaving only the moving links and their constraints. Click and drag the center link up and down, and watch the center point trace a straight line.
