(II) A grinding wheel is a uniform cylinder with a radius of
8.50 cm and a mass of 0.380 kg. Calculate (a) its moment of
inertia about its center, and (b) the applied torque needed
to accelerate it from rest to 1750 rpm in 5.00 s. Take into
account a frictional torque that has been measured to slow
down the wheel from 1500 rpm to rest in 55.0 s.
(I) A 52-kg person riding a bike puts all her weight on eachpedal when climbing a hill. The pedals rotate in a circle ofradius 17 cm. (a) What is the maximum torque she exerts?(b) How could she exert more torque?
(II) A small rubber wheel is used to drive a large potterywheel. The two wheels are mounted so that their circularedges touch. The small wheel has a radius of 2.0 cm andaccelerates at the rate of 7.2 rad/s and it is in contact withthe pottery wheel (radius 27.0 cm) without slipping. Calculate
