In its final analysis this criticism is summed up in the assertion that in strictness thought is only the indeterminate unity and the action of this indeterminate unity.
With this method the structural analysis of static and kinematic indeterminate foldable systems is conducted and the kinematic bifurcation points of pin-connected foldable structures along motion pat.
The general formula which could be applied to compute the constraint reaction to statically indeterminate structures with elastic bearings is obtained by analysis of a computing result.
