Methods of stress-analysis have found wide application in the fields of structural and mechanical engineering where quantitative evaluation of internal forces and movements are an absolute requirement for useful, economical, and safe design. Used in conjunction with sound design principals, stress analysis has made possible the complete blue-printing of engineering structures where particular end-use properties of these structures are desired and can be formulated. p4. 收起
