For the last 26 years during National Engineering Week (the first week of March) civil engineering students from both Canada and the United States gather at the Troitsky Bridge Building Competition at Concordia University in Montreal. In order to enter a bridge in the competition the teams must meet these requirements: “Each team must design & build a bridge with an open span of 1 meter and composed solely of Popsicle sticks, white glue, dental floss and toothpicks” and have an overall weight limit of 6 kg. Previous winners have built bridges weighing only 1.29 kg (2.8 lbs).
This year’s winning team is from McMaster University in Hamilton, Ontario and they are aptly named “The League of Extraordinary Gentlemen.” Their extraordinary bridge successfully carried 2,733 kg, beating the event’s previous record by 200 kg. The League of Extraordinary Gentlemen also beat out the reining champions from UQAC in Chicoutimi, Ontario who have held the title for the past six years.
The bridges were judged on aesthetics and originality of design (10 points), booth layout and presentation (10 points), ultimate load carrying capacity (20 points), predicted ultimate load carrying capacity (25 points), structural efficiency (25 points) and predicted mode of failure (10 points). The League of Extraordinary Gentlemen had a total score of 92.49 out of 100.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
