Hertzian contact stress with PrePoMax

Hertzian contact stress occurs when two curved, elastic bodies are pressed together. German physicist Heinrich Hertz formulated this theory in 1881 to calculate the resulting pressures and deformations. The theory assumes linear-elastic, isotropic materials and frictionless contact.

There are two primary configurations:
- Point Contact: Sphere on sphere or sphere on a flat plane.
- Line Contact: Cylinder on cylinder or cylinder on a flat plane.

Assembly and kinematics of lifter arm | FreeCAD

Kinematics is the study of the motion of bodies and systems. In FreeCAD, simple kinematic models and motion analyses can be created using the "Assembly" tool.

"Assembly" in FreeCAD is an integrated workspace for creating assemblies and defining relationships between individual parts. It allows you to create assemblies with various types of connections (joints) and define relative motion between parts.

Transparency | Changes the transparency of windows

Transparency is a simple Python tool. Use "Select window" to select a window, then adjust the transparency by moving the slider between 0 (fully-transparent) and 255 (non-transparent). The "Reset" button sets the transparency of all windows to 255. Click "Exit" to reset and close the tool.

Chebychev-Grübler-Kutzbach Criterion | OpenModelica

Chebychev – Grübler – Kutzbach Criterion is the determination the number of degrees of freedom in a kinematic chain when rigid bodies are connected by mechanical joints. The number of degrees of freedom of all rigid bodies in the chain is reduced with the number of joint constraints connecting these bodies.
----
Chebychev – Grübler – Kutzbach Kriterium ist der Bestimmung der Anzahl der Freiheitsgrade in einer kinematischen Kette, wenn starre Körper durch mechanische Gelenke verbunden sind. Die Anzahl der Freiheitsgrade aller starren Körper in der Kette verringert sich mit der Anzahl der Gelenkbeschränkungen, die diese Körper verbinden.
