Querry on a MATLAB Post

I have across a very useful description of pendulum model in the webpage, http://ctms.engin.umich.edu/CTMS/index.php?aux=Activities_Pendulum

However,

I could not make out how they have actually attached or mounted the rotary potentiometer shaft on the pendulum rod.

A better image is also available in the link http://ctms.engin.umich.edu/CTMS/index.php?aux=Index_Activities

How can we ensure just the shaft to rotate and not the cap? Any thoughts?

The About item in the upper-right section of that page has a subitem Contact. I recommend that you use that to ask the authors and/or maintainers of that webpage for more information about the example.
