Top 10 Biggest Design Errors Engineers & Architects Made

  • Published on Apr 17, 2017
  • Designing things is hard. You must go to school for years doing un-fun things like math and physics to become qualified to build most things professionally. And because humans are humans and not calculators, mistakes are bound to occur. In this video I’ll show you 10 bizarre and noteworthy examples of these human errors.

    The bridge/spaghetti analogy doesn't make sense?!?! When you cook a "spaghetti Noodle" it doesn't put holes in it.
    Are you saying that if they had boiled the bridge in water for 10 minuets it wouldn't have collapsed?
    (Not to mention the fact that the bridge collapsed due to it having the same resonant frequency as the wind)
    (or the fact that the bridge swayed and twisted around like a piece of spaghetti before it collapsed(because it was SOOOO solid)

    #7 - I think you are wrong here ... the reason it gave away was resonance, certain wind speed made the bridge resonate (aeroelastic flutter) and hence it's 'tone' got higher and higher till it collapsed ... nothing to do with spaghetti / noodles.

    So many bits wrong in this video.
    #10: Aircraft carrier runways:
    The speed of early aircraft was slow enough that they needed less space to land, but as jets came along, they needed more space to land because of their higher speeds.
    Aircraft would either be lauched, or recovered, not both at the same time... however an angled deck could allow both the happen at the same time making them more efficient.
    #9 Tecoma Narrows bridge:
    The collapse wasn't because it was solid (if it was solid, it wouldn't have been able to flex in the way it did before collapse.
    It collapsed due to resonance caused by the bridge moving but the resonance frequency growing to the point the bridge structure couldn't withstand.
    This phenomena wasn't known when it was built.
    #7: DeHaviland Comet's square windows.
    Although it's true that a squared corner adds a greater level of stress, the're more than the simplistic description in this video.
    First, the Comet was the first jet airliner and few aircraft up to this time were either pressurised, or flew at high altitudes. This is why the unpressurised DC3 is still in service today, but generations of pressurised airliners have been scrapped because they've outlived their pressure cycle limit.
    Secondly, the Comet used punch riveted holes (which aren't as precise as drilled holes) and this added small fractures around the hole resulting in a crack that could grow from the stress.
    Every airliner crash brings lessons which may reveal phenomena that weren't known about and were unexpected, but there's a difference between a design blunder, and not anticipating something that wasn't known.
    #4 isn't an engineering blunder, nor an architectual one... it's a perfectly good functioning building... it's just not appropriate for baseball.
    I bet it would be fine for cricket or basketball, volleyball and hundreds of other sports!
    #2 also doesn't count as an engineering or architectual blunder... it was a site management blunder, which is significantly different.
    #1 A revolutionary new design takes a while to evolve.
    The Peral couldn't use petrol or diesel engines at this time because they weren't reliable, so electric motors were used powered by batteries.
    The displacement and air tanks were adequate and it was generally considered successful... which is pretty impressive since it was experimental technology.
    Ultimately, submarines didn't become properly viable until the turn of the 20th century, and in particular WW1.

    There is slight catch with carrier runways though. Sure, I do not think it's the best design, but you must realize that most of them were built before war, when the catapult to launch planes was not a thing. Those planes needed much longer piece of runway to take off. So even though the 9 degree runway would exist, it wouldn't be of much use back then. In fact, in the end it would only add target area, thus making them easier to hit. As a matter of fact, that is still problem of those giant carriers. They are so huge you couldn't miss them even by accident.

    "Design Errors"?
    Be Amazed, would you call the Wright Flyer of 1903 a "Design Error" because it couldn't carry 300 people?
    The aircraft carrier was first built just after WW1, the first angled deck was tested after WW2 and became standard in the mid 50's with the HMS Ark Royal being the first Aircraft Carrier being purpose built with an angled deck, so there was about thirty years of the "Though Deck" AC with prop driven aircraft which worked relatively well until jet aircraft appeared and a Royal Navy officer came up with the "Angled Deck" to deal with their particular foibles.
    This would be better termed a "Developmental Phase".

  • Ellis Birt

    The Tacoma Narrows bridge collapse was not due to it being inflexible. It was down to resonance and turbulence. The air passing around the deck caused lift on the deck, just like an aircraft wing. That, in itself was not a problem but, as the deck moved the lift reduced. That combined with gusts close to the resonant frequency if the deck led to the deck oscillating like a string when it is plucked. The bridge was known as "Galloping Gertie" because this was a common occurrence. One day the gusts were at exactly the right frequency to resonate the bridge enough for it to collapse.
    Modern suspension bridges do indeed often have open trusses on the deck, but that is only one way the design the decks to avoid lift from being generated.
    The millennium Bridge in London had a similar problem, It stared to move and that made pedestrians walk in step with the movement. That in turn amplified the movement. The bridge was closed while engineers added dampers below the deck

    About the rod story.
    It wasn't about the weight on the rod. It was about the weigth on the nut. By spliiting the rod in two, the nut/hole wich was only intended to carry the weight of the upper bridge now had to carry the weigth of both bridges. Both bridges were stacked with people when it collapsed.

    So dont give me bullshit about double checking

  • Jared Bonter
    Jared Bonter 7 days ago

    The Tacoma bridge didn't collapse because wind couldn't blow through it. It collapsed because the structural members of the main deck all had the same harmonic response. Due to this, the main deck started to undulate which continued to build on itself, snowballing out of control. Modern bridge design intentionally designs dissimilar structural members specifically to counteract this phenomenon

  • Owen Taylor

    Sorry, but the biggest load of bs in this one is the DeHavilland Comet crashes. Those planes crashed (with the causes found by the investigators) because of stress cracks due to the pressurisation of the cabin upon takeoff and the decompression of it on landing. So many of those aircraft were just ticking time bombs, and the fact that the windows (in your analysis) were the reason behind them is absolutely laughable. Dear God, get someone to proof read your scripts, save yourself the embarrassment.

    The DeHavilland Comet's square windows failed because of continual pressurisation and de-pressurisation, not because of high speed flight. However the result was the same and a great lesson learnt the hard way at the cost of many more lives than 56.
    The Lotus Riverside Building which fell over may have been initially due to unwise excavation but the real reason it fell was the miserably inadequate foundations which were simply not strong enough to anchor it to the ground. No proper steel reinforcing was placed in the concrete footings, which were apparently just cement-filled cardboard tubes.!

    Some of the information in the video is purely pulled out of thin air or an article on the internet, just because it's on the internet it doesn't mean it's true. The Tacoma bridge didn't fail because it 'didn't have any holes'. As an engineer, I can easily say the Tacoma bridge failed due to a phenomenon known as natural resonance. The bridge itself had no damping characteristics and the winds created a force that caused the bridge to resonate at its natural frequency. The best way to fix something like that is to change it's damping characteristics or increase the degrees of freedom of the bridge. The bridge did not fail because it didn't have any 'holes'. Please fact check your videos as it reaches out to so many people.

    The comet airplane was involved in 26 hull loss accidents. 13 of these were crashes that resulted in 426 deaths not 56. The crashes were not blamed on square windows but on riveting, which put microfractures on the corners of the windows. From there, it was a matter of metal fatigue. While to suggest square windows should belong on a plane is not by any means unreasonable, the way this was presented was poor, unresearched, and misleading.

    Just a quick fact as most of the corrections have already been made, The De Havilland Comet was the first jetliner. At the time, powerful softwares that engineers use today for stress simulations (eg. Ansys) were not available and hence the windows were sharp edged since probably nobody expected such large stresses. Today metal fatigue is well understood and simulated before production begins and the comet is one of the reasons for this advancement.

  • JellyBeans2001

    The reason the aircraft boats were that was was because the planes had propellers and were not jets, they needed that extra length of take off space to get in the air, and couldn't have done that on a shorter angled runway. And yes some were able to pull up and try again.
