Important problems in the linear theory of the equilibrium of beams of isotropic elastic material have usually been approached by the so-called semi-inverse method, whereby a system of stresses or displacements is guessed and subsequently verified.
Mahalaga problema sa guhit teorya ng balanse ng beams ng isotropic nababanat na materyal na may karaniwang been approached sa pamamagitan ng tinatawag na semi-kabaligtaran na paraan, kung saan ang isang sistema ng mga problema o displacements ay guessed at pagkatapos napatunayan na.
