## Details

The Freudenstein equation gives an analytical solution for the geometry of a four-bar linkage. The steering mechanism in this Demonstration has two four-bar linkages:

1. the trapezoidal steering linkage between the two wheel steering arms

2. the linkage between the steering wheel shaft and the steering linkage
