P. 4238. A thin-walled plexy cylinder of mass M and of radius R can rotate freely without friction about its horizontal axis. Inside there is a solid rubber cylinder of mass m and of radius r. What is the period of the motion of the system when the rubber cylinder is displaced a little from its equilibrium position? It can be assumed that the rubber cylinder rolls without sliding inside the plexy one.
Sorry, the solution is published in Hungarian only.
