[Lab Disks] Two identical uniform solid disks are stuck together at their rims, as shown, and rotate about an axis perpendicular to the plane of the disks ( page) that passes through their point of contact. (a) Find an expression for the moment of inertia of the two disks about this rotation axis through their point of contact. Give your answer in terms of the mass m and radius R of each disk. [HINT: You'll need to use the Parallel Axis Theorem along the way.] (b) Now suppose the same disks are stuck together by a layer of Velcro of
