    Graduate How can I accurately determine the stiffness of a joint using polynomial curves?

    Stiffness is non-linear, so there is no formula I can use.. Dr Courtney, I think I see what you are saying... Tabulate the results of each equation (ie for rotation, M=) then average the actual results, plot this average and fit a polynomial to this? If I'm reading you right, I think that could...

    Graduate How can I accurately determine the stiffness of a joint using polynomial curves?

    Hi all, I'm hoping someone can help me out with this problem. I am following an example of a previous report to analyse some test results, but am having trouble with this step. The tests plot moment-rotation curves of a horizontal member fixed into a vertical member. You run 5 tests, and for...
