i really need to know which truss brudge design will work
the material used for it is basswood. you are allowed to cut it. it already is 1/8 inches thin
The answer to that question is not simple and probably is not going to be what you expect. The truth is, I cannot answer the question. There are too many variables that are not being defined.the strength ratng is determined by the material strength of what you build it with
Example:
Is the the Pratt truss or the Warren truss stronger? Actually, the answer is up to you. You can make the Warren truss stronger. Or you can make the Pratt stronger. It depends simply on the strength of the wood you use. You can use 2×4’s to build the Warren, and toothpicks to build the Pratt. Obviously the Warren is going to be stronger in this case.
