What material has the best strength to weight ratio?
The problem with your question is that you need to define “strength”. There are a lot of different ways to measure “strength”. Ie what quirkie suggested. Other ways are: -how long can you stretch it before it breaks -how much weight you can put on it before it stretches a certain amount -if you turn the rod sideways, how much weight can you suspend from the middle -are you talking about compressive or tensile “strength” -is this a one time test or a durability test (some materials can survive a really heavy stress, but only a few times, while others can survive a lighter stress, but many many times) These, and many other properties, are unique for each material and in no way connected to each other. Before we can give you a reasonable answer, we need to know exactly what you’re asking.
