^{3}, and an elastic limit of 39 MPa. On the other hand, cast iron has more resistant values; specifically, it is also an isotropic material, having a Young’s modulus of 120,500 MPa, Poisson coefficient of 0.30, density of 7150 kg/m

^{3}, and elastic limit of 758 MPa (only elastic material models were used and the elastic limit was only pursued in order to determine the safety coefficient, as can be found in Section 3.2).

^{6}N.mm. It is actually based on a hypothesis that is not entirely true, since part of the energy generated in the electric motor is lost in friction and resistance. However, if these data are taken as the maximum achievable torque when analyzing the model, it will be in a situation of von Mises stresses on the safety side (Figure 13).
