For the truss under the following 3 loading conditions, determine the minimum cost of each truss based on the following:

* wood (popsicle sticks) - $100/stick

* cable (thread) - $10/section

note that all members of the truss are the same length. given this information, it doesn’t matter what length you use, or what "x" is, but if it , just make up numbers, i. e. length of 5" and x of 10lbs. in class we will be using members that are approximately 6" long and weights that are approximately ½ lb, although on the weights we can just add more to get the desired effect.
