Basin equations of Karman and Chien (given in, Torsion with Variable Twist, Jour. Aero. Sci., vol 13, no. 10, Oct, 1946, pp. 503-510) are solved by representing the shape of a torsion box by means of a Fourier series. The coefficients of the series are determined by conventional methods. Angles of twist, longitudinal stresses, and shear stresses are determined in terms of the series coefficients.
