Okay guys, a lot of people had said that a bridge design contest would be fun, so here we go! If you are interested, please fill out this form in the comments below:Reddit Username:Nickname (if none, Reddit name will be used):Are you a professional Engineer?What design software are you using?The design limitations are as follows:Bridges must fit into a 4-inch x 6-inch x 4-inch area, with solid beams across the 4-inch edges, so that the bridge can rest on blocks over a gap. Also, please make sure that you have a beam on the bottom of your bridge, near the center, to hang the weights off of.Bridges must be able to be “functional,” meaning that they must have a 2-inch wide section straight across for “cars” to move across, and it cannot have a solid top, but beams are allowed. You do not need a solid surface for the “cars,” but this rule is just there to stop people from making solid beams.All bridges will be printed on the same printer at the same settings using the same materials. Pieces will be printed out of PETG at 100% infill. If your design is over 50 grams, it will be disqualified or the infill will be reduced until it is at 50 grams (support material will not count).Designs must be submitted by the deadline: August 15, 2016.1st place in both of the two categories (professional engineer and amateur) will receive a roll of Atomic Filament PETG, and 2 rolls of Atomic Filament will be donated to a local high school engineering program in their name. If anyone else would like to add items to the prize pool, let me know!If we have received more than 50 entries, we will judge them in virtual destruction to choose the strongest 50.If there is a lack of interest, we will cancel the contest and return any items added to the prize pool.The winner will be selected based on what bridge can support the most weight on its load-bearing beam. Weight will be measured using Vernier laboratory equipment.Let me know if you have any questions, or if you have suggestions. http://ift.tt/2a13WJP
