Find the final angular velocity of the smaller cylinder

Reference no: EM13285700

Two cylinders, made from the same material and having the same length, have radii r1 and r2 with r1 > r2. Both are free to rotate about their respective axes. The larger cylinder is initially rotating with angular velocity ?o. The smaller cylinder is moved until it comes into contact with the larger one. Eventually the frictional force causes both cylinders to rotate with constant angular velocity but in opposite directions. Find the final angular velocity of the smaller cylinder. Are any dynamical quantities conserved in this case? Please use words along with your calculations.
