The author studies a problem on large deformations of dilatation, torsion and bending of naturally twisted rod loaded by end forces and moments. Partial solutions are found for elastostatic equations representing two-parametric families of finite deformations and possessing the property that on these deformations the initial system of three-dimensional nonlinear equilibrium equations is reduced to the system of equations with two independent variables.
