Method for analysis of planar motion of system with rigid and extremely flexible components via analogy with contact problem of rigid bodies

Recent years have witnessed attempts to employ a system with rigid and extremely flexible components (SREF), usually consisting of strings, membranes, and so on, to realize huge structures for spacecraft in orbit. In general, such flexible components have two states, i.e., with and without tensional...
