- Abstract
During study of the dynamics of rotation we introduce the concept of moment of inertia of a rigid body about an axis of rotation and then particularized for those with symmetry about the axis. The formulas for calculating the moments of inertia of these bodies are used in solving problems, but it is important to provide students the method to determine experimentally and to verify the theoretical expressions. This is precisely the goal commonly designed for lab intended for such purposes. In the paper three experimental arrangements, characterized by different levels of automation in measurements and processing data and are evaluated and compared among them using for this purpose a selected group of parameters from expert criteria. For each case, provide recommendations to enhance the use of this assembly as an attractive lab in the system being developed for Mechanics.
