| Abstract: | Applying the mathematical transform between polar coordinates system and rectangular coordinates system,the coordinal transform among the stresses and directly seeking the solution of the derivation of the equilibrium equations,we can obtain the solution of the derivation of the equilibrium equations. This essay reveals the advantages and disadvantages of those three methods. |
