<p>This simulation visualizes geometric properties and static internal forces in a loaded Michell cantilever anchored at two points.
Michell geometry is parameterized by total length (Length), distance between attachment points (Height), and number of truss layers (n) - additional x and y scaling may be applied.
Internal static forces are calculated using the <a href="https://en.wikibooks.org/wiki/Statics/Method_of_Joints" target="_blank">method of joints</a>.
<br/><br/>
Drag on the applied force to change its magnitude and direction.
Use the sliders to adjust geometric parameters of the Michell truss.
Mouse over a beam to see more information about its properties.
