Analysis is given of bending stresses caused by torsion in a box with variable cross section and loading. Recurrence formula leads to set of equations identical in form with three-moment equations. Special formulas are provided for full-width cutouts and carry-through bays. Short-cut method in solving system of equations sufficiently accurate in practical stress analysis is indicated, which may be applied without knowledge of the general method.
