Bicycle Physics

Science of Cycling: Explained SimplyThis guide is designed for both the mathematically challenged and the math proficient cyclist who want to understand the science behind their favorite activity. In fact, all science buffs are welcome to explore an activity that has grown by several orders of magnitude since 1970..To explain basic principles, we'll use Excel style formatting to separate the variables, making the calculations easier to follow. If you can use a hand calculator, you should even be able to evaluate other situations by following the examples.Once basic principles are established, they will then be combined to generate the formulations for creating the modeling tools. The math here will be more rigorous but understanding it will not be a requirement for using the spreadsheets themselves. Hyperlinks to the spreadsheets will allow the reader to evaluate their own performance under different scenarios. These formulations would also allow those with sufficient math skills to generate their own situations.The spreadsheets will calculate the factors that govern a bicycle in motion, including:The effect riding position has on wind resistance (frontal profiles).How different road surface properties impact rolling resistance.The physics behind why a high spin rate provides for optimal power transfer.Calculate energy expenditure and power generated during both hill climbs and level biking.The Laws of Physics are universal! After characterizing your performance here on Earth, you can then use these same principles to predict your cycling performance on other worlds like Mars or the Moon. While real off-world cycling awaits future generations, the tools provided will let you calculate your hypothetical cosmic performance today—it's a fun thought experiment.Both English and Metric units of measurement will be evaluated Read more
