18. Figure P10.18 shows the drive train of a bicvcle that has wheels 67.3 cm in diameter and pedal cranks 17.5 cm long. The cyclist pedals at a steady cadence of 76.0 rev/min. The chain engages with a front sprocket 15.2 cm in diameter and a rear sprocket 7.00 cm in diameter. Calculate (a) the speed of a link of the chain relative to the bicycle frame, (b) the angular speed of the bicycle wheels, and (c) the speed of the bicycle rela- tive to the road. (d) What pieces of data, if any, are not necessary for the calculations? Rear sprocket Pedal crank Front sprocket Chain Fiqure P10.18
