1. The problem statement, all variables and given/known data I have a practical coming up and I have to research the method and calculations. I will be given an irregular lamina that I need to use as a compound pendulum in an experiment to determine the gravitational acceleration, g, as well as the moment of inertia (Io) of the lamina. I will know the mass of the lamina as well as the center of gravity. I need to use the lamina as a pendulum and obtain readings for the period of oscillation and distance between center of gravity and the point of rotation. I then need to perform appropriate calculations and plot a linearised graph to verify the relationship between the variable suggested in equation 3 below. I have no idea what the appropriate calculations are. 2. Relevant equations Equation 1: T = 2*pi*(I/mgl)^1/2 (Period of oscillation equation) Equation 2: I = Io + ml^2 (Parallel axis theorem) Equation 3: T^2*l = 4*pi^2*(Io/mg + l^2/g) (Insert equation 1 into equation 2 and rearranged) 3. The attempt at a solution At this stage I have worked out how to calculate where the center of mass is using a plumb line and bob, but I cannot find what appropriate calculations I need to do. I need to know the process of what calculations I need to perform once I have me readings in order to solve for the two variables g and Io.
