Homework Help: Physics

Posted by Jeras on Friday, November 30, 2012 at 3:37am.

My experiment setup was like this:
i48.tinypic. com/14n31pl.jpg

FYI, there is sandpaper between the ruler and the wall. I calculated the coefficient of friction to be 0.468. Is that correct?

A second question asks that as the hanging weight is moved closer to the wall, what other variables change (tension, normal or horizontal force, friction or vertical force, coefficient of friction) and which remain the same? I'm not sure. Is it the friction that increases as the torque caused by the hanging weight increases? And everything else remains the same?

No one has answered this question yet.
