I'll preface this with saying I'm an Industrial Designer, not an engineer. I also build workshop furniture as a hobby, which this question is in reference to. I'm building a motorcycle lift table. I'm curious, is there a chart that compares things like tubing material, size, strength and weight? i.e. If I wanted to replace a steel tube frame with aluminum I could use this chart to figure out what diam/wall tube I would need to be comparable in strength and if there would be any weight savings in doing so.
