1. The problem statement, all variables and given/known data A uniform disk turns at 3.7 rev/s around a frictionless spindle. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk . They then both turn around the spindle with their centers superposed. What is the angular frequency in rev/s of the combination? 2. Relevant equations L = Iω 3. The attempt at a solution I was trying to relate the angular velocity to this but I don't think that's the correct approach. For example, on my second attempt I had: ω = L / (1/6)(M)(l)^2 (3.7 rev/s)(6) = 22.2 rev/s I'm having trouble finding a connection.
