Salakazi Racing’s KTM nitro methane motorcycle/dragster does the quarter mile in 6.7 sec, with a terminal velocity of 196 mph. One key for reaching these speeds is an automatic three-disc, four-stage clutch fitted with a Proworx digital controller. That controller is pre-programmed for optimal speed given the racing conditions it encounters. Inside this clutch, there are a few tiny but critical devices. Among them are a pair of RM22 encoders from Gloucestershire, United Kingdom-based Renishaw. The encoders are both fast and precise enough to monitor speeds up to 30,000 rpm. One monitors the position of the crankshaft in the engine, while the other measures the clutch speed. When these two values are compared, clutch slippage, traction and road conditions can be determined with high precision.
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.
