Youtube channel “Real Engineering” explains the science behind why airplane windows are round.
The problems caused by cabin pressurization didn’t develop until the introduction of the first commercial jet powered aircraft, The De Havilland Comet. It entered service in 1952 and initially proved to be a massive success, but just one year into service catastrophe struck. Three Comets suffered fatal mid-flight disintegrations and the entire fleet was grounded until the cause was identified.
The root of the problem was double-edged. The introduction of jet engines required planes to fly even higher in order to make the fuel hungry engines economically viable (less drag in the upper atmosphere means less fuel is needed). As a plane increases in altitude the external atmospheric pressure lowers to a greater extent than the internal cabin pressure. This creates a pressure differential that causes the fuselage to expand ever so slightly. Engineers accounted for this, but the effects of repeated pressure cycles over time were not well known at the time. Over thousands of cycles and metal begins to fatigue and cracks can form at high stress locations.
The effects of stress concentration were also not well understood at the time. Stress concentration occurs when the flow of stress is interrupted. Square windows, in contrast to modern oval windows, provide a significant barrier to the smooth flow of stress. Because of this stress peaks at the sharp corner of the window, and this is exactly where investigators determined the origin of failure to be.
These combined phenomenon proved to be fatal. Today all airliners feature oval windows to avoid this stress concentration and comprehensive fatigue testing is required before a plane can be approved by the FAA. We often learn the most from our failures, this is particularly true for advancements in the field of engineering. These are now two basic concepts that every materials engineer is taught, these events allowed us to further our understanding of materials and prevent further failures.
On January 6th, 2016, Ian Coulson proposed to his girlfriend in the geekiest way I’ve seen in a while. Watch.
IS THIS the greatest proposal of all-time? Ian Coulson, from Brighton, enlisted the help of his friends – and his soon to be father-in-law – to propose to his girlfriend Lizzy by acting out iconic scenes from some of their favourite films, including Lords of the Rings and Star Wars. The heartwarming video sees Ian have a light saber battle with Darth Vader, slap Gollum and out run a Black Rider from Lord of the Rings on horseback – and ends with him popping the big question to Lizzy. Ian shot the initial footage in November last year and then screened it for Lizzy on January 6, 2016, recording her reaction live. Stars Wars has always been a big part of the couple’s relationship, as Ian revealed that on their first date they watched episodes one to six of the sci-fi saga.
Atari is bringing a collection of 100 classic console games to the PC. It’s promising a range of usability upgrades to the originals.
The games will be packaged in a single title, Atari Vault. Among those already announced are Asteroids, Centipede, Missile Command, Tempest and Warlord.
The company describes the games as re-imagined, though it’s not clear how extensive any gameplay changes will be. What is known is that there’ll be a change to user interfaces, support for the Steam controller, and both online and local multiplayer where appropriate. As you’d expect, there’ll also be a worldwide leaderboard system for comparing high scores.
The initial release is planned for both Windows and the Steam system in the spring, with Mac support added later. Pricing hasn’t been revealed yet.
As always with such retro projects, it’s the selection of the 100 titles that may be the most important factor. There’s always the risk it will be a few of the better-known titles and then a lot of padding, with other top games held off for an expansion or second edition.
While some of these games have been available (if not always officially) in emulated versions before, one selling point this time is that the Steam controller might offer the closest modern peripheral equivalent to the trackball used for some Atari 5200 games, most notably Centipede and Missile Command.
Youtuber berlagawesome built this crazy insane Rube Goldberg machine so that it could deliver him a single can of soda. The man spent around 140 hours (over 3 months) to create this setup, which failed 114 times before he finally got it to work. Impressive.
Adam Savage gets special access to one of the spacesuits from The Martian to study and document it for his personal replica project! Here’s Adam’s gleeful first impressions after opening the suit’s shipping crate and appreciate for some of the fine fabricated details seen in person.
Jay Flatland and his friend Paul are currently in the process of applying to get their Rubik’s Cube solving robot, which can solve a cube in just 1 second, in the Guinness book of world records. Be sure to check it out in action in the video above.
