Rack and pinion
In SAM the rack and pinion element is defined by toothed wheel and a rack.
Gear
In SAM the gear element is defined by two toothed wheels, including internal tooth. A combination of multiple gears forms a gear box.
Belt
In SAM the belt element is defined by two pulleys and a connecting belt. Optionally it forms an open belt, like a rope on a pulley or an assembly line. In an advanced layout it can be used to transform a rotation into a translation.
Slider
The slider looks like a bar, but one end node is free to move on the bar. Here also is demonstrated how to apply mass on an element. The position of mass and inertia is defined by the user.
Beam
The beam (bar or rod ) is the most common element in SAM. It connects 2 nodes in a linkage mechanism, and it transduces force and torque. The end nodes may be fixed to world as an axis or act as a gliding node. At the end nodes angular fixation to other elements can be added. This demo also demonstrates the use of the beam as a linear actuator or a hydraulic cylindre. Therefore elongation is added to the beam.
Two position syntehsis
A part is copied at two positions, and based on mechanism construction rules a four bar linkage mechanism is synthesised. SAM demonstrates the mechanism reaches the two prescribed positions exactly
