#8 – Ices, Ices, We All Fall Down!

…in which Randy and Mike both re-discover the value of studded tires.

  • We each experimentally verify our hypothesis that slick tires on ice do not provide significant lateral traction when descending, and bruises are likely to result.
  • Somehow this leads to a discussion of the physics of turning and stability of bicycles (and motorcycles!).  Mike referred to research done on bicycle dynamics a few years ago, published in the journal Science, showing that neither trail nor gyroscopes are necessary to make a bicycle stable.  There are some good video demonstrations of it, and explanations of the research by both Arend Schwab and Andy Ruina.
  • Randy explains the best method of using training wheels.
  • We discuss the importance of anticipating inattentive drivers about to start their journeys.
