This paper makes a comparison of the internal responses of beam component and circular shaft component, that is the comparison of the value of the normal stress on beam’s cross section in beam’s pure bending and the value of the shear stress on circular shaft’s cross section in its torsioning, and through the qualitative analysis of the experimental phenomena, and connecting with their quantitative expression in three aspects of geometric relation, physical relation and static relation, and with the help of differentiation, integration and other analytical tools in advanced mathematics, obtains some expressions with similar forms and interlinked ideas.
