Calculating Torque to Move Object

  1. Dec 30, 2008 #1
    I have a bicycle with 26 inch diameter wheels that weighs 200 pounds with the rider on it. the bicycle has two wheels. How much torque would this bicycle need to maintain a constant speed of 20mph? Assuming no air resistance?

    What do you think? Is there any other form of rolling resistance to be overcome by this torque?

    Is this homework/coursework? If so, I can move this thread to the Homework Help forums. In any case, we don't solve homework-type questions here on the PF. Show us your thoughts and calculations, and we can provide some hints and tutorial help.
