One may notice that, in practice, the available cone deformation mode from elasticity remains necessarily small. Telescope grazing incidence mirrors are, at least, always optically surfaced from a passive cone geometry.

10.2.4 Radial Thickness Distributions and 4th-Degree Flexure

We consider various cases of obtaining a fourth-degree flexure where a uniform load is applied all over the tubular surface.

• Uniform load in reaction with simply supported ends: Similarly as in the latter Section, we denote the reduced axial ordinate x = [12(1 - v2)]1/4x/a and the dimensionless flexure W. Let us consider a flexure now expressed by
