Info

The two instant centers I₁₃ and I₂₄ move as the fourbar linkage goes through a cycle of motion. I₁₃ is always at the intersection of links 1 and 3, and I₂₄ is always at the intersection of links 2 and 4.

Note that in the Working Model file the coordinates of  I₁₃ and I₂₄ are entered as functions instead of constants.
