Free-Flex(reg) Pivot frictionless, precision cross-spring bearing is for use wherever limited angular rotation bearings are required for angular travel up to ±30 degrees. The bearings require no lubrication or maintenance; are dirt insensitive; and eliminate the inaccuracies of friction, stiction, wear, radial clearances, and backlash. The pivot has a high radial and axial stiffness to maintain repeatability to ±0.000001 inch in one plane of motion, with low hysteresis, center shift, and thermal drift.

Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
