Conventional rim brakes on a bicycle apply an approximately 1-kN force at the rim of the wheel, some 60 cm in diameter. Disc brakes, which are becoming increasingly popular, apply roughly 4 kN near the outer edge of a 200-mm-diameter disc. Estimate the torques to determine which braking system exerts the greater torque and by approximately what factor?
