To shed light on the correlation between J max and C , the J max - C relation is determined and shown in Fig. 3. This relation is also strongly non-linear (Fig. 3). A significant reduction of J max is seen in Fig. 3. The rate of the reduction, however, decreases. Next, the investigation is focused on the evolution of the maximum J with varying of the mass, m p . The relation between J max and m p is reported in form of a graph in Fig. 4. The first that captures the attention is the non-linearity of the J max - m p relation (Fig. 4). Another interesting observation is that J max grows at a rising rate (Fig. 4).

The evolution of the maximum J with varying of F q is also a subject of exploration in the current article. This exploration results in the J max - F q relation whose graphic is reported in Fig. 5. The relation is non-linear (Fig. 5). Besides, J max has a growing rate (Fig. 5). 4. Conclusions The results obtained by the current analysis can be summarized as follows: 1. The relation between J max and n is strongly non-linear. 2. The J max rises with n at a rapidly growing rate. 3. The J max - C relation is strongly non-linear too. 4. The J max reduces with C at a decreasing rate. 5. The J max grows with m p at a rising rate. References Ariga, K., Ji, Q., Hill, J. P., Bando, Y., Aono, M., 2012.
