Parameterized Four-Bar Linkage

This example models a four-bar linkage. Hyperlinks in the model let you change the lengths of the links enables it to model a parallelogram, crank-rocker, or drag link linkage.

Parallelogram Linkage

The plot below shows the mechanism parameterized to be a parallelogram linkage. The moving ends of links 1 and 3 trace two circles with the same diameter.

Crank Rocker Linkage

The plot below shows the mechanism parameterized to be a parallelogram linkage. As link 1 moves in a full circle, link 3 oscillates back and forth.

Drag Link Linkage

The plot below shows the mechanism parameterized to be a drag link linkage. Link 1 and 3 move in full circles of different sizes.
