Can you please solve this problem?

15. We have meshed a solid geometry using 10-node Tetrahedral elements (Figure 4) and have applied a fully fixed constraint (all translations (TX, TY, and TZ) and all rotations (RX, RY, and RZ) are fixed) to one node of the structure. a) What action is enforced by the RX, RY, and RZ constraints? b) Would you expect the structure to be sufficiently constrained for a static stress analysis? c) If not, how many nodes would have to be constrained to "fix" the model for a static stress analysis? 10 5 9 2 Figure 4 A 10-node tetrahedral element
