Help with balsa wood bridge?
We are doing projects and want a bridge that can make the greatest weight. Here are details 3/32x3/32 wood balsa bridges must be free of the maximum mass stnading: 13grams maximum length of 22 cm minimum length of the deck and the minimum clearance between the springs at the base of 14 cm width 3 cm maximum width of 3 cm in maximum deck height of 8 cm of at least 5 cm in the center of minimum 5cm space period of at least 3 cm wide can only use wood glue and other materials not only two sticks of wood can be laminated as the load is applied 3cmx10cm a test block to add more pressure to the weight until it breaks the bridge. Thanks I really need help finding a good armor all these requirements and a good way to support the joints and the base. Thanks! The use of wood glue for my tail What is a good armor to use for my bridge if weight 3cmx10cm a block?
