A simulation of a linkage mechanism to trace a straight line based on the four bar linkage, and related to the Watt straight-line mechanism in model S-24 or that due to Chebyshev shown in Model S-30. The straight line is generated by an extension of the center link. This is an abstract model where pedestal and supports have been removed, leaving only the moving links and their constraints. Click and drag the sliding joint and watch the free end trace an approximate straight path along part of its motion.
