Like a tadpole losing its tail, the Aquastrada Delta amphibious vehicle
cruises the shore, then climbs up onto it. Created by a team of engineers in
Carmel, CA, the vehicle achieves top speeds of 100 mph on the road and 45 mph on
water, says chief designer Gary Gere. With a 139-inch wheelbase, the 18-foot,
2,830-pound Delta is no minnow.
Aquastrada International Corp. is patenting or has patented many aspects of the vehicle design, and will display it at the New York International Boat Show this month. Look for production models in 1997. The price: $150,000.
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.
