A solid cylinder of mass M and radius R is resting on a horizontal platform (which is parallel to the x-y plane) with its axis fixed along Y -axis and free to rotate about its axis. The platform is given a motion in the X -direction given by x=Acos(ωt). There is no slipping between the cylinder and the platform. The maximum torque acting on the cylinder during its motion is

A solid cylinder is placed on the end of an inclined plane. It is found that the plane can be tipped at an angle θ before the cylinder starts to slide. When the cylinder turns on its sides and is allowed to roll, it is found that the steepest angle at which the cylinder performs pure rolling is ϕ. The ratio tanϕ/tanθ is
