Homework Help: Time period of a pendulum consisting of a rod and bob

  1. Jul 18, 2013 #1
    1. The problem statement, all variables and given/known data
    How should I find the time period of a pendulum which is made up of a rod of length l fitted with a bob of radius r at its one end and the other end being pivoted to the wall?

    2. The attempt at a solution
    Actually having problem with calculating the moment of inertia of the system, which I think is the very step to solution of the problem.

    You'll need both the moment of inertia and the centre of mass. What equations do you have for moment of inertia that might be relevant?
