Define the joints that connect the parts of the crank slot model. Revolute, slot, and cylindrical joints form the moving joints. The base of the model is fixed to the ground via a fixed joint.

The following figure shows the parts of the model, with the joints listed to the right:

Revolute -- Base to Bolt1 Fixed -- Rod1 to Bolt1 Fixed -- Rod1 to Bolt2 Fixed -- Rod2 to Bolt3 Cylindrical -- Rod2 to Bolt2 Slot -- Base to Bolt3 Fixed -- Ground to Base

All joints are available via the MPC184 element's KEYOPT(1) setting and, in some cases, the KEYOPT(4) setting. For more information, see Connecting Multibody Components with Joint Elements.
