Ka kakaretso, likhutlo le likhutlo tsa lihlahisoa tse bōpiloeng li lokela ho etsoa phetoho ea R, hobane tekanyo e kholoanyane ea ho atolosa ka likhutlong tse bohale ho bonolo ho baka botenya bo sa tšoaneng ba marako, 'me likhutlo tse bohale li boetse li bonolo ho hlahisa khatello ea khatello, le phetoho ea R. ea lihlahisoa ka etsa hore lerako botenya ba lihlahisoa junifomo.
Eketsa moralo oa sebopeho ho compression, tsitsipano le torsion
Ka litlhoko tse fapaneng tsa sehlahisoa, moralo o mong oa sebopeho sa compression, tsitsipano le torsion le tsona li ka eketsoa:
1. Haeba u batla ho eketsa khanyetso ea longitudinal ea sehlahisoa, u ka etsa li-stiffeners tse ling ho latela tataiso ea khatello ea kelello.
2. E le ho ntlafatsa ts'ebetso e khahlanong le ho oa ha lihlahisoa, bokaholimo bo ka boela ba etsoa hore e be mohaho oa arc o loketseng ho imeloa kelellong le ho tlatsoa ka likhopo tse matlafatsang.Lehetla la lihlahisoa tsa botlolo le lokela ho sekamela, eseng le bataletseng le le otlolohileng.
Ka kakaretso, botlaaseng ba botlolo bo entsoe ka sebopeho sa concave ho eketsa matla le botsitso ba ho beha.Ka mohlala, hangata re bona libotlolo tse nang le oli e jeoang tse nang le libopeho tse ling tsa concave-convex holim'a metsi, tse ke keng tsa eketsa matla a 'mele oa botlolo feela, empa hape li thusa ho ngola matšoao a khoebo.
