Thrill-seeking engineers are now taking advantage of new propulsion systems in their mission to scare people to death. Top Thrill Dragster, at Cedar Point Amusement Park in Sandusky, OH—the world's largest and fastest roller coaster—uses a hydraulic launch system to hurtle passengers from 0 to 120 mph in the 4-second launch period and to pull the 16 passenger trains up a 420-ft hill. Thanks to PLCs and an advance monitoring system, up to six trains can run on the tracks at the same time.
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.
