     they most likely used clear or white glue, because hot glue isnt that strong of a hold.

   its a wrong way to test a bridge lol…..

   the correct way is to attach a rod through a hole in the bridge with a plate on top. A cable will be attached and you must wind it to increase the weight.
   The test that you did tests the top of the bridge, but cars and people will only go on the deck. LOL

     I agree that there are better ways to test the bridge (winding cable instead of loading up paving blocks). However, in this design the “cars and people” deck is the top of the bridge.

     In a bridge building competition, the rules will (or should) define exactly how the bridge will be tested. You then design the bridge around that particular test.

     Rightly or wrongly, the rules for this bridge design specified that it would be loaded from a central point using a 1″ square steel tube. The bridge design was optimised to support a single central load.

     Had the load been applied at an off-centre load point or in some other manner than a point load, the bridge would likely have failed sooner.
