Bicycles convert force into torque (pedal to axis), torque into force (axis to chain using the front gear), force into torque (chain to back wheel using back gear), and finally torque into force (wheel on road), and that accelerates the bike.
Bicycles convert force into torque (pedal to axis), torque into force
(axis to chain using the front gear), force into torque (chain to back wheel using back gear), and finally torque into force (wheel on road), and that accelerates the bike. If you make the front gear smaller, is it easier or harder to pedal (explain in terms of forces/torques)? If you make the back gear smaller, is it easier or harder to pedal?
