The Electrak 150 is the first of a new series of low priced, quiet, linear actuators from Warner Electric. A key feature--and one that helps achieve an IP-55 rating for outdoor use--is the lightweight plastic housing made from recyclable material. However, on the inside and all-metal thrust system carries all of the load. They are available in three sizes with maximum dynamic load capacities ranging from 110 lbs to 450 lbs, and maximum static loads from 330 lbs to 900 lbs. Speeds of up to 2.8 in/sec are offered with strokes up to 16 inches. Other features include: a breather tube in the wiring harness to allow operation without drawing water through the seals on the cover tube; an anodized, corrosion-resistant aluminum cover tube; and optional potentiometer or optical encoder.

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.
