Relations between efforts in work and automatic gates

How to correlate efforts in work and automation

You need to take into account all the parameters for calculation. And only then do calculations.

As curved coordinates of the point M of the median surface of the membrane, the longitudinal coordinate X and the length of the arreure of the transfer line C, counted from the curve formed in the intersection of the middle surface with the plane U = 0.

By virtue of the hustling of the shell in the longitudinal direction, the parameters of the A1 and A2 parameters for the specified curved coordinate system can be adopted 1, and the curvilinear coordinate system can be considered approximately as orthogonal with constant curvature.

The ratios between the efforts, moments and deformations of the middle surface for the structurally orthotropic membrane. Equilibrium equations in movements.
