1. The problem statement, all variables and given/known data The pendulum shown below right consists of a uniform disk with radius r = 20.0 cm and mass m = 1.2 kg attached to a uniform rod with length L = 40 cm and mass M = 0.8 kg. What is the period of the motion? 2. Relevant equations T = 2∏√(I/mgL) 3. The attempt at a solution I dont know what to plug into what.
