performed during the lab included investigation 1; an investigation into the moment of inertia of Maxwell’s wheel and investigation 2; an investigation into the dynamics of Maxwell’s wheel. Data & Analysis Investigation 1 In order to calculate the moment of inertia of Maxwell’s wheel the moments of inertia of the disk and the axle had to be added to each other. In order to perform this task various quantities and qualitative data were calculated and collected. The mass of Maxwell’s

Caliper‚ measure and record the height and diameter of the cylinder. • Using proper formula to determine the volume of the cylinder. A cylinder with radius r units and height h units has a volume of V cubic units given by V = πr2h‚ (r = ½ d). • Calculate density according to d = mass/volume. • Compare your calculated densities with the literature value for the density of Aluminum and determine the % error for each calculation. B. Add water to a graduated cylinder‚ read the volume (mL)‚ carefully
