Find the uncertainty in the moment of inertia. Moment of inertia of a disk depends on mass and radius according to this function l( mr) = 1/2 mr ² . Your measured mass and radius have the following uncertainties Sm = 0.01 kg and Sr = 0.25 m. What is is the uncertainty in a moment of inertia, SI, if the measured mass, m = 4.86 kg and the measured radius, r = 0.89 m?
