Description: The paper proposed a method for calculating the amount of effort twisting wire stretching used when fixing the wheel and tracked vehicles on rail cars. The calculations were performed with the elastic-strain state of the wire in the process twisting stretch. Consider the scheme of forces acting on the twist in the wire section. The formulas for which is determined by the value of the bending moment and torque acting sectional wire twist.
