Actually, it didn't because I used two segments of 2x4 for the weight on the double wide strip and stacked two 2x4 segments of the same length for the weight on the single wide tread. The only weight difference is the weight of 3.5"x6" of rougtop tread and 3.5" of two-inch aluminum angle iron, the total of which could hardly combine to cause an additional 2N of frictional force.
This would be one of those "if you don't know, don't state something as fact" moments.

I had one of our animators edit the video, and I just got it sent to my email unfortunately, it's a download link so I am unable to view it on my iPod
. However, I trust he did a good job and so here's the link:
