註釋Three particular problems of the strength of the structure of spacecraft and their boosters are discussed and the relationship between structural form and the purpose of the vehicle is described. It is shown that highly symmetric space frameworks can be kinematically unstable. A simple proposal is made how to appraise the probable magnitude of the initial deviations of the middle surface of the wall of a circular cylindrical shell from the exact cylindrical shape and it is demonstrated that this appraisal leads to good agreement between theory and experiment regarding the buckling stress when the shell is compressed axially. Finally it is shown that localized weld flaws of a geometric nature reduce the bursting pressure of cylindrical pressure vessels to a much lesser extent than was anticipated on the basis of studies of the effects of axisymmetric deviations.
