I've been trying to find a cheap/used tensile testing machine that we could do some serious trials on but no luck and the new rigs run a couple of grand. When people like Lefty say they have done this type of test I'm inclined to believe them, but it would be nice to see the results published.
If anyone knows of any sources on the web or in books, please shout. I'm talking about real stats - multiple trials - statistically significant sets of results etc.
To do this type of test justice would be a lot of effort but I think it would be very worthwhile. The absolute and relative performance of different knots on different brands of tippet, for different diameters would be extremely useful.
Maybe the manufacturers already do this?
Any engineering students (or better still teachers) out there with access to lab facilities? This would make a great college/high school applied physics project.
