…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.
