Lonke uthotho ngokwezifiso Screw

Inqanaba lokusebenza kwe-bolt liqulathe iinxalenye ezimbini zamanani, ezimele ngokulandelelana ukomelela kwe-bolt kunye nomyinge wemveliso yezixhobo. Umzekelo, intsingiselo yeebholithi ezinenqanaba lokusebenza kwe4. mm2; Inani kwinxalenye yesibini (6 ngo-4.6) lizihlandlo ezili-10 zomyinge wesivuno sezinto zebhawudi, okt FY / Fu = 0.6; Imveliso yamanani amabini (4) × 6 = "24") yi-1/10 yenqaku lesivuno esichazayo (okanye amandla esivuno) (n / mm2) yezinto zebolt, oko kukuthi, FY ≥ 240n / mm2.

Ngokuchaneka kokuvelisa, iibholiti eziqhelekileyo zesakhiwo sentsimbi zinokwahlulahlulwa zibe ngamanqanaba amathathu: A, B kunye ne-CA iBakala B licocekile, elisetyenziselwa iimveliso zoomatshini, kwaye ibakala C li-bolt erhabaxa. Ngaphandle kokuba kuchazwe ngenye indlela, iibholiti eziqhelekileyo zesinyithi ziqhelekileyo iibhola C eziqhelekileyo kunye nokusebenza kwe-4.6 okanye 4.8.
