1. Inqanaba lamandla
Inqanaba lamandla eloriiibholiti ze hubidla ngokumiselwa ngokwezinto zabo kunye nenkqubo yonyango lobushushu.Ukulinganisa amandla aqhelekileyo aquka i-4.8, 8.8, 10.9, kunye ne-12.9.La mabanga amele i-tensile, shear kunye neempawu zokudinwa kweebholithi phantsi kweemeko ezahlukeneyo.
Iklasi ye-4.8: Le yibholithi yamandla aphantsi, ifanelekile ngamanye amaxesha aneemfuno zamandla aphantsi.
Iklasi 8.8: Eli libakala lamandla ebholithi elixhaphake ngakumbi, elilungele umthwalo onzima ngokubanzi kunye nezihlandlo zokusebenza ngesantya esiphezulu.
Iklasi ye-10.9 kunye ne-12.9: Ezi zimbini zimbini eziphakamileyo zisetyenziselwa kwiimeko apho amandla kunye nokuqina kuyadingeka, njengamaloli amakhulu, izithuthi zobunjineli, njl.
2. Amandla okuqina
Amandla okuqina abhekisa kuxinzelelo oluphezulu ibholithi enokumelana nokuqhawuka xa iphantsi kwamandla okuqina.Amandla okuqina eebholithi zelori yeehabhu zelori anxulumene ngokusondeleyo nenqanaba lamandla ayo.
Amandla okuzibamba okuqhelekileyo odidi lwe-8.8 yeebholiti eziqhelekileyo yi-800MPa kwaye amandla esivuno yi-640MPa (umlinganiselo wesivuno 0.8).Oku kuthetha ukuba phantsi kweemeko eziqhelekileyo zokusetyenziswa, ibholithi inokumelana noxinzelelo lokuya kuthi ga kwi-800MPa ngaphandle kokwaphuka.
Kwiibholiti zamabanga aphezulu amandla, njengeKlasi ye-10.9 kunye ne-12.9, amandla okuqina aya kuba phezulu.Nangona kunjalo, kufuneka kuqatshelwe ukuba amandla e-tensile awawona aphezulu angcono, kodwa inqanaba lamandla e-bolt elifanelekileyo kufuneka likhethwe ngokuhambelana nendawo ethile yokusetyenziswa kunye neemfuno.
