It has been five years and literally tens of thousands of man-hours of work. Finally, the American Society for Testing and Materials (ASTM) F-24 technical committee has wrestled a new standard for the amusement park industry from the clutches of a variety of task forces evaluating everything from appropriate restraint devices to—for the first time—g-force limits. High g-forces have been thought to pose the risk of brain injuries. This standard is unique not only for its comprehensiveness, but also its global reach (not to mention that consensus building always takes time.) "It was a huge effort, really the biggest single standard that the amusement ride and device committee has worked on in its 25 years," says Greg Hale, chief of safety at Walt Disney World Resort and an outspoken advocate of safety standards. Hale and co-workers devoted hundreds of hours of their own time to this effort. Known as the Standard Practice for the Design of Amusement Rides and Devices—Z9591Z to those in the know—the standard piggybacks on an existing ASTM standard, but is unique in that it addresses detailed design criteria intended to assist engineers in designing rides that make people only feel like they are in peril. Active committee members hail from Australia, Bahrain, Brazil, Canada, France, Germany, India, Italy, Japan, Russia, Switzerland, The Netherlands, the U.K., and the U.S.—making for a truly global effort and ensuring that the best design practices from around the world made their way into the standard. Guess it's a small world, after all.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
