We are trying to build a bridge made from paper, water based glue and cotton strings. The bridge must be able to hold 5kg; however, we would like it to hold more weight. The weight of the bridge should also be taken into consideration.
So we came up with numerous designs and we finally decided on a ring design one of my friends came up with which is able to hold 7-10 kg of weight when it is being stretched. I attached pictures of the ring design with where the deck would be placed ; note the real bridge would be 50cm long with numerous strings.
Now we can't decide on how to connect those ring structures holding the deck up to the table. A straight line attached to a pillar on the table is not strong enough ...
Any suggestions?
