Homework Help: Strange constant, rolling cylinders.

  1. Dec 18, 2014 #1
    1. The problem statement, all variables and given/known data
    We have experimented on rolling cylinders and have gotten the function for a rolling cylinder but have gotten a strange constant from experiment.

    2. Relevant equations
    [tex]t = 2\sqrt{\frac{l}{g}(1+\frac{r}{R})\frac{1}{\sin{\theta}}}-0.5[/tex]

    3. The attempt at a solution
    Is this constant wrong? Which we think it is. We got it from linearisation from matlab. It doesn't make sense and probably is the fault of experiment. Any thoughts?

    Can you tell us more about the experiment and define the parameters in your Relevant equation?
