The always amazing Zen Pencils pays tribute to Jones in this cartoon. In a video clip, Jones recites a great quote that his art instructor would begin classes with: āAll of you have one hundred thousand bad drawings in you. The sooner you get rid of them, the better it will be for everyone.ā In his memoir, Chuck Amuck, Jones followed up the quote with: āThis was not a discouraging statement to me, because I was already well into my third hundred thousand.ā
Released in 1952, the de Havilland Comet was the worldās first commercial jetliner. But engineers did not know at that point that a forgotten feature ā square windows ā would be a disastrous design.
We often learn the most from our failures, this is particularly true for advancements in the field of engineering. Unfortunately for the engineers in the aviation industry, the prices to pay for failure are high. The flip-side of this unforgiving industry, is that it consistently provides learning opportunities for engineers, because failure is not an option when peoples lives are at risk.
One of the greatest examples of this occurred during the development of cabin pressurisation. The problems caused by cabin pressurisation didnāt 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.
Schecter Guitar Research and Wylde Audio announce signing a world-wide distribution deal. Schecter will distribute Wylde Guitars, the creation of legendary guitarist Zakk Wylde (Black Label Society, Ozzy Osbourne), via their distributor network covering over 70 countries, which also includes handling fulfillment of the guitars in the USA.
āWe are extremely proud to be working with Zakk and Wylde Audio on this endeavor,” states Schecter Guitar Research Executive Vice-president Marc LaCorte. āZakk has been incredible in recognizing what he wanted in his own brand and bringing the best possible product to the market.ā
The first offering from Wylde Audio, including the Odin, War Hammer and Viking models, are set to debut at the 2016 Winter NAMM. Zakk has already been putting the prototypes through their paces at recent Black Label Society shows. āI’m very excited for the launch of Wylde Audio in 2016,ā Wylde states. āFor me, itās the next logical step. You start as a player, manager, VP of Team Operations, then Team Owner. I’ve surrounded myself with super talented people to make this vision become a reality and having Schecter on board as our distributor is going to allow me to bring Wylde Audioās boutique quality of craftsmanship to the next level.ā
Here’s the video footage of Zakk Wylde’s January 22 press conference at the NAMM show in Anaheim, California about his latest creation, Wylde Guitars.
With appropriate extraordinary skill, Led Zeppelinās John Paul Jones can teach anyone about the art of music production. Dave Grohl — along with some of his rock counterparts — wonders when perfection became so important.
Go into any bookstore, and you’ll be amazed at the amount of different colouring books are on display – for kids and adults. Sugoi Books has released a new, unofficial Drake coloring book, while you’re waiting for your hotline to bling. Did I use that right?
In 2013, David Bowie shared his 100 favorite books on his official website, ranging from classic novels to biographies of musicians and everything in between. How many have you read?
Rock icon Iggy Pop and Josh Homme of Queens of the Stone Age recorded an album in secret and announced it for the first time tonight on The Late Show With Stphen Cobert.
Joshua tree. ā¦Itās lovely because you have a chance to sort of make mistakes and figure things out and find your own path. When you make a record, nobody is aware youāre doing it, youāre kind of making it for each other and youāre kind of there to excite and dazzle each other.
The pair later debuted the song āGardeniaā from the new album, which will be available March 18, 2016.
