Analysis: Models of rolling resistance

We’ll use the simplest model of rolling resistance, based on our dry friction approach.

Although we used this simple model, making the experiment work was not simple at all. Many subtleties arose, such as using the rope around a bollard concept and dealing with a sloping table.

Data from the experiment are given in the Downloads section below.
