Problem 249 A vertical cylinder of radius R is rotating with a constant angular velocity o along with holders A and B about the axis as shown The vertical movement of cylinder is restricted by the holders Oil is only in between the bottom of cylinder and surface as shown The thickness of the oil layer is t Assume that coefficient of viscosity is n and that cylinder can only rotate if there is no friction elsewhere Find the power required to overcome the viscous resistance A R
