The angular speed of a moving particle of the model was relatived to curveture tensor to derive the curveture components and torsion of helices. In order to include usual applications, the center line of a complex wire rope was considered as straight as well as curved. Based on the results of this research, the expressions of stress-strain relation, compatibility condition and equilibrium requirement could be more realistically stated.
