The discussion centers on calculating the torque required for a bicycle with 26-inch diameter wheels and a total weight of 200 pounds, including the rider, to maintain a constant speed of 20 mph. The participants emphasize the importance of considering rolling resistance in addition to torque calculations. While the initial question lacks detailed calculations, it invites further exploration of the physics involved in maintaining speed on a bicycle.
PREREQUISITESPhysics students, bicycle enthusiasts, mechanical engineers, and anyone interested in understanding the dynamics of bicycle performance and torque calculations.
gearhead said: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?
