To learn about Degrees-of-Freedom and Mobility.

To learn more about dyads (also called Assur Groups)

➔Kinematic-Chains: Degrees-of-Freedom, Mobility

➔6-bar Kinematic-Chains: Crank + R-R-R + R-R-R - Pin-Joints.

➔6-Bar Kinematic-Chains: Crank + R-R-R + R-R-P - Pin-Joints and one Slide-Joint.

Experiment with different possibilities of the three joints in a dyad.

Also, change the Motion-Part from a Rocker to a Slider.
