Torque To Move Bicycle

  1. Dec 31, 2008 #1
    The following attached file is a free body diagram for a bicycle. Please excuse the crudity of the drawing, I drew it on paint. The bicycle weighs 100 kilograms with the rider on it and has 26 inch wheels. The bicycle is at rest. The static coefficient of friction between the wheels and the road is 0.5, thus making the force of friction 490Newtons. How would i calculate from here how much torque I would need to get the wheel to start turning and where exactly (at what point on the wheel, be it the outside rim or on the hub where the gears are) would i need to apply that calculated torque?
