The Simple Method to Confirm the relation between the geometric deformations in a structure

This article analyzes and discusses the relation ship between the geometric deformations in an engineering structure (no matter it is static determinate or static indeterminate.).It points out that the traditional geometric-deformation-drawing method is complicated and has shortcomings.Therefore an analytic method based on the converse thinking manner and higher math is presented.The new method is simpler than the geometric method and is easy mastered.
