Estudo experimental do momento de inercia de um cone (Experimental study of the moment of inertia of a cone)
2005
In this work, it is shown a different way to study the moment of inertia of a body. It is proposed an experiment that allows establishing how the inertia of a cone depends on its mass and geometry. The parameters are determined as follows: the exponents and the constant of the conventional equation of the cone’s moment of inertia, starting from measurements of frequency or current. Three cones of distinct masses are used, two of them 10,0 cm of diameter, while the other ones 6,0 cm diameter. The obtained results show that the system and the procedure used can be an alternative in the teaching laboratories.
