Mathata a bakoang ke lerako le tšesaane la bumper le tharollo
Ho fokotseha ha bumper ho bonolo ho baka deformation warping, 'me warping deformation ke phello ea ho lokolloa ha khatello ea kelello ka hare.Li-bumpers tse nang le marako a masesaane li hlahisa khatello ea maikutlo ka hare ka mabaka a fapaneng nakong ea mekhahlelo e fapaneng ea ho bopa ente.
Ka kakaretso, e kenyelletsa haholo khatello ea maikutlo, khatello ea mocheso, le khatello ea ho lokolloa ha hlobo.Khatello ea maikutlo ke khoheli ea ka hare e bakoang ke likhoele, liketane tsa macromolecular kapa likarolo tsa ho qhibiliha tse lebisitsoeng ka tsela e itseng le ho phomola ho sa lekaneng.Tekanyo ea ho shebana le eona e amana le botenya ba sehlahisoa, mocheso oa ho qhibiliha, mocheso oa hlobo, khatello ea ente le nako ea ho lula.Botenya bo boholo, bo theola tekanyo ea ho sekamela;ha mocheso oa ho qhibiliha o phahame, o theola tekanyo ea ho sekamela;ha mocheso oa hlobo o phahame, o theola tekanyo ea ho sheba;ha khatello ea ente e phahame, tekanyo ea ho sekamela e phahame;ha nako ea ho lula e le telele, tekanyo ea ho sekamela e ea eketseha .
Khatello ea mocheso e bakoa ke mocheso o phahameng oa ho qhibiliha le mocheso o tlase oa hlobo ho etsa phapang e kholoanyane ea mocheso.Pholiso ea ho qhibiliha haufi le sekoti sa hlobo e potlakile 'me khatello ea ka hare ea mochine e ajoa ka tsela e sa tšoaneng.
