Amakuru y'Ikigo
Inganda zUbushinwa zifasha ibigo gukoresha ikoranabuhanga ryamakuru mugutezimbere, kumva amakuru yinganda, no kuguha serivisi zoroshye kandi zihuse: imbere ya silindrike ya mpandeshatu.

Hariho urutonde rwibice bitandatu bishingiye ku gukomera, imbaraga zingana, gutanga umusaruro, nibindi byinsinga za screw, arirwo rwego rwimyenda itandatu. Kubikoresho bitandukanye, ibyiciro bitandukanye byimbere ya mpande esheshatu bisabwa kugirango bihuze nabyo. Imbere ya mpande esheshatu zose zifite amanota akurikira: imbere ya mpande esheshatu zigabanyijemo ibice bisanzwe kandi bikomeye-ukurikije imbaraga zabo. Ibisanzwe bya mpande esheshatu bivuga icyiciro cya 4.8, mugihe imbaraga-ndende zingana zingana na 8.8 cyangwa hejuru, harimo 10.9 na 12.9. Icyiciro cya 12.9 heckagon sock bolts mubisanzwe yerekeza kumutwe wumukara wa hexagon sock imitwe ifite ishusho yazunguye, ibara risanzwe an
ibisabwa
1. Imbaraga zumwanya wizina wibikoresho bya bolt bigera kurwego rwa 400MPa;
2. Ingano yumusaruro ugereranije nibikoresho bya bolt ni 0,6; Umusaruro wizina wibikoresho bya bolt ni 400 × 0,6 = 240MPa.
Imbaraga zikomeye zifite imikorere ya 10.9, ikozwe mubikoresho byakorewe ubushyuhe, irashobora kubigeraho:
1. Imbaraga za nominal tensile imbaraga za bolt igera kurwego rwa 1000MPa;
2. Ikigereranyo cyimbaraga zumusaruro wibikoresho bya bolt ni 0.9; Imbaraga zumusaruro wizina ryibikoresho bya bolt bigera kurwego rwa 1000 × 0.9 = 900MPa.
Igisobanuro cyibikorwa byo murwego rwimbere ya mpande esheshatu ni urwego mpuzamahanga ruzwi. Bolts hamwe nibikorwa bimwe, utitaye kubintu byabo ninkomoko itandukanye, bifite imikorere imwe, kandi amanota yimikorere agomba guhitamo kubishushanyo mbonera.
Itondekanya rya mpande esheshatu ni nkiyi, kandi igiciro ku isoko rwose kizahinduka bitewe nurwego. Mubisanzwe, imbaraga-ndende zingana zingana rwose zihenze cyane kuruta ibisanzwe bisanzwe. Amanota ane akunze gukoreshwa ku isoko ni 4.8, 8.8, 10.9, na 12.9.
Umutwe wa mpande esheshatu uri hagati kandi uhetamye, bishobora gutera ibibazo bikomeye. Kurugero, uhereye kumiterere yibicuruzwa, ntabwo bishimishije muburyo bwiza. Ikindi kibazo nuko kibogamye, gishobora gutuma byoroshye urushinge rwibikoresho biva. Ikibazo gikomeye cyane gishobora no kuganisha kumurongo wibibazo nko kumena ibice bitandatu.
