A potter's wheel is rotating around a vertical axis through its center at a frequency of 2.0 rev/s . The wheel can be considered a uniform disk of mass 4.7 kg and diameter 0.30 m . The potter then throws a 2.8-kg chunk of clay, approximately shaped as a f
A grinding wheel is a uniform cylinder with a radius of 8.50 cm and a mass of 0.480 kg . Calculate the applied torque needed to accelerate it from rest to 1750 rpm in 5.10 s . Take into account a frictional torque that has been measured to slow down the w
