A Rocker is a Part that rotates around a Pin-Joint. Motion-values at the input-connector to a Motion-Dimension FB controls the position and motion of the Rocker.

GST-5-501

To add a Rocker:

1.Add a Motion-Dimension FB to a Pin-Joint

2.The Base-Value = 40º

3.Add a Motion FB to the graphics-area.

4.Add a Linear-Motion FB to the graphics-area.

5.Drag wires to connect the Linear-Motion FB to the Motion FB to the Motion-Dimension FB.

To edit the FBs, double-click the FB icons, or see How to open an Element's dialog.

A Crank is a derived term for a Rocker that rotates at constant speed.

GST-5-502

The Crank:

1.Add a Part, Pin-Joint and Motion-Dimension FB

2.Edit the Base-Value with the Motion-Dimension FB dialog

3.Add and connect a Linear-Motion FB and, optionally, a Gearing FB, to the input of the Motion-Dimension FB

A Slider is a Part whose motion is controlled to move along a Slide-Joint.

GST-5-503

To add a Slider:

1.Add a Motion-Dimension FB to a Slide-Joint

The initial position, here 110mm, is the 'Base-Value'

2.Add a Motion FB to the graphics-area

3.Add a Linear-Motion FB to the graphics-area

4.Connect the Linear-Motion FB to the Motion FB to the Motion-Dimension FB
