The Root Section of a Swept Wing—A Problem of Plane Elasticity

The methods of N. I. Muskhelishvili are used to obtain the stresses in an approximately square plate, subject to concentrated forces at two opposite corners, acting in the direction of the diagonal, and to certain shear-stress distributions along the sides. These shear-stress distributions have been chosen to conform approximately with those observed at the corresponding boundaries during tests on a 45-deg sweptback tube with ribs normal to the leading edge. Numerical results, involving loading parameters, are presented in the form of tables and graphs. Use of the numerical results is illustrated by application to a wing under varying degrees of torsion and bending.
