Reply Joseph Mach says: May 27, 2019 at 7:03 am I wish more schools did this. Too many of the "top" universities focus completely on analytical work. Reply Stefano Bruno says: May 27, 2019 at 7:03 am Se lo avessero caricato al centro, avrebbe retto meno carico. Mi sembra che abbiano usato un bel trucco.

I think that the dising is not simetric and because of that it is not going to be 100% effective. Reply Angel's Scroll says: May 27, 2019 at 7:03 am So interesting! Reply schmudge says: May 27, 2019 at 7:03 am Chinese made Popsicle sticks or locally made? I hear all your bridges have the non compliant reinforcing steel lol. Reply Anze Ciuha says: May 27, 2019 at 7:03 am They must measure in the middle. I can create bridge that can take 200kg+ if you measure 1cm from left or right. This is cheatting. Reply Swimmy SwimmSwimm says: May 27, 2019 at 7:03 am Makes zero sense to measure it's wright causality from the point at which they hung the weights from… Fail on their part… Seriously.. Reply Juan Luis López Moreno says: May 27, 2019 at 7:03 am Good job estimating the failure load! But I don't think is fair.. The bridge should be loaded it in the middle of the span. In this case, the bridge is asymmetric and they will get less bending moment for the same amount of load. Reply Marc Frank says: May 27, 2019 at 7:03 am has someone ever used generative design for this? Reply Informedia Tech says: May 27, 2019 at 7:03 am fuckin love it..now do the same to my neighbour house Reply Ruskyviewer says: May 27, 2019 at 7:03 am Please take a tip from a professional cameraman and use a tripod. For me there is nothing more irritating than shaky images like this. It makes me queasy trying to watch it. Reply Slim Pickens says: May 27, 2019 at 7:03 am Fire that camera man!!! Christ all mighty that was horrid! Reply スリンキーSlinky says: May 27, 2019 at 7:03 am Murray? Pris- oh, that's me. Reply Guy DeCou says: May 27, 2019 at 7:03 am when you can teach an engineering class but can't operate a fucking finger nail clipper…yikes… Reply DATING HARLEY QUINN says: May 27, 2019 at 7:03 am THATS 110kg……………….! Reply Christian Rubarth says: May 27, 2019 at 7:03 am Those unexpected long finger nails at 0:58 are almost killing me. Reply Owen Dougherty says: May 27, 2019 at 7:03 am They are applying the load in the wrong spot. It should have been put on the top, it would have held more weight Reply Benjamin Davoult says: May 27, 2019 at 7:03 am the bridge folded in several location, this is a good sign that the distribution of the tension was fairly good. It would be even better if the bridge literally exploded everywhere at the same time, meaning that all the efforts were all over the place, evenly.when I did this exercice back then (with spaghetti), we used 2 buckets of water and poor in from one to the other gently, then weight the bucket after the bridge breaks. Seems more convenient than the loads you are using.good show, loved it.Thanks. Reply Zencognito says: May 27, 2019 at 7:03 am The piss poor camera work flirts with motion sickness. Pity that. Otherwise, I would have watched more than two minutes of it. Reply Aristocles Athenaioi says: May 27, 2019 at 7:03 am Geez the jerking and bouncing image from the camera almost made me nauseous. I had to stop watching because I couldn't get a focus on the truss bridge. Reply Zachary Rec says: May 27, 2019 at 7:03 am We did a similar project in high school physics… you received 1 Manila folder and were told to span a set gap. (I think it was 9 inches). Had to be an A frame type with a centered load. Smart folks used different glues, one even used hollow tubes and filled with hot glue. Meanwhile i honeycombed my main struts and carried twice as much weight as the solid strut with 1/5 the weight Reply Robert Barnes says: May 27, 2019 at 7:03 am For future reference, U of A — this could have been a very good, compelling bit of advertising for your program. Instead it's kind of an embarrassment. Next time, if you're doing something that may well end up presented to the world on YouTube, record it properly. This is a mess and, frankly, a bit of an insult to the viewers. Second, add some narration rather than throwing some text up on the opening shot. A description of the project with some context, particularly the "record" they're shooting at. Yeah, it's meaningless, but competition, some kind of goal engages peoples' interest. And we still don't know how much weight it supported. Next time, call out the amounts of weight as it's added, and leave the guy yelling "1— 2— 3…" at home. What was that, anyway? There seemed to be some sort of urgency to getting the weights on (at least I assume those discs were weights — you never said). Apparently they beat "the record." Yay. How much was it? Was the result close to their prediction? It would have been nice if you had given a 15 second overview of HOW they calculated their load projection. And HOW did the structure fail, and at what point? How well did that match their projections? Some super slow motion video would have been enlightening, as well as entertaining. Did they use the result of this exercise to make design changes in the bridge? I would really have liked to see that. From the READ ME at the end, I deduce that one purpose of this project was to advertise the University. This exercise is done at many university engineering departments around the world. This may sound nit-picky, but I can guarantee you that the same bridge built by undergrads at Berkeley would look a lot better, more cleanly designed, more symmetrical with fewer odd bits sticking out at random — more "professional". Now, maybe it was designed purposely to be asymmetrical. If so, explain why. I don't doubt that you have a top tier program, but prospective applicants are going to be impressed by superficialities. From a few feet away, this thing looks like a middle school science project. You didn't do university recruitment any favors by sending this video out into the world. But you might have. Look on it as a missed opportunity.Does your university have any kind of program in broadcast arts. If so, why not engage them in this next year, let them use it as a project for their students. The outcome would undoubtedly be better than this disaster. Reply Chris Snyder says: May 27, 2019 at 7:03 am What I like is how close the lad’s unprotected eyes are to the potential splintering of popsicle sticks. I’m glad there was no injury this time but please insist on safety glasses for future attempts. Otherwise I enjoyed the video. Reply You Can Do It!!! says: May 27, 2019 at 7:03 am Keep the camera still. I'm getting an headache Reply Jalzerio Figueira says: May 27, 2019 at 7:03 am Lol Reply Bruce Roger Morgan says: May 27, 2019 at 7:03 am Fascinating project. Terrible video! Why couldn't he show the weights being added? Who the hell was the guy calling out 1 – 2 – 3? What did that mean? What's 1087N in Kg? What about some commentary? Reply LordCarpenter says: May 27, 2019 at 7:03 am Nicely done, team!Next assignment… Camera Stabilizer. Reply Patrick Warfel says: May 27, 2019 at 7:03 am Very nice! That's about 244 lbs. I had to do a similar thing working with my young teen's his science class. Sadly, it was all balsa sticks and no screws were allowed. But we fell farrrrrr short of this. It's a superb way to learn about structures Reply UMBRELLA Corp. says: May 27, 2019 at 7:03 am exelenteeeeeeeeeeeeeeeeeeeee!!! Reply Railgap Esoterica says: May 27, 2019 at 7:03 am IF only there were some way to stabilize videos with software after you've made them – some kind of service – ideally, it would be free and easy to use, maybe right on the video hosting web site somewhere… but that's just a pipe dream, right?
