A steel six-wheel shopping cart with nylon webbing siding and child seat won the ninth annual National Engineering Design Challenge for a safer shopping cart, sponsored by JETS, a national, non-profit educational organization that promotes educational excellence in math, science, and technology in high schools. To prove its stability, three students balanced on the buggy's side during competition. The cart stood motionless. A novel six-wheel design is the key to the cart's steadiness. On the standard cart, the turning wheels are in the front and the pivot point is in the back, creating front-wheel steering. The diameter of the smallest circle it can make, therefore, is twice the cart's length. The Queen of Carts' two center wheels not only act as stabilizing wheels and keep the cart going straight, but also are the pivot point. The cart can turn from either end--from front or back around the center wheels. Also, while standard carts carry most of the load in the front over the turning wheels, making them difficult to maneuver under heavy loads, the Queen of Carts can easily carry loads up to 1,200 lb. Alysse Beutel, Patrick Flannery, Judith Luckie, Jessica Rudy, and Rebecca Wilson from West Perry High School in Elliottsburg, PA designed the Queen of Carts. FAX: (212) 967-7292
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
