Computation of cantilever airplane wings

Computation of cantilever airplane wings

Date: July 1, 1925
Creator: Thalau, K
Description: The purpose of this treatise is, first of all, the determination of the effect of variously loaded spars on one another, since the neglect of this effect would present an economically very unfavorable computation method. The system of spars and cross-bars alone (whether solid or built-up) does not matter at first, the original assumption being that the spars are rigidly braced by the cross-bars.
