Imirongo ibiri yumurongo uringaniye

Ibisobanuro byimirongo ibiri yumurongo wuruhererekane cyane harimo urunigi rwerekana urunigi, umubare wihuza, umubare wizunguruka, nibindi.

1. Urunigi rw'umunyururu: Icyitegererezo cy'imirongo ibiri y'uruhererekane rusanzwe rugizwe n'imibare n'inyuguti, nka 40-2, 50-2, n'ibindi. Muri byo, umubare ugereranya uruziga rw'urunigi, igice ni 1/8 santimetero;ibaruwa yerekana imiterere yuburyo bwurunigi, nka A, B, C, nibindi. Iminyururu itandukanye ikwiranye nibikoresho bitandukanye bya mashini kandi igomba guhitamo ukurikije uko ibintu bimeze.
2. Umubare wibihuza: Umubare wihuza ryumurongo wikurikiranya wikurikiranya ni numubare.Kurugero, umubare wihuza ryurunigi 40-2 ni 80. Umubare wihuza uhindura muburyo butaziguye uburebure nubushobozi bwo gutwara iminyururu, kandi bigomba guhitamo ukurikije ibikenewe.
3. Umubare wibizingo: Ubugari bwihuza bwumurongo wikurikiranya ya kabiri ni 1/2 santimetero cyangwa 5/8.Ubugari butandukanye bwibihuza bikwiranye nibikoresho bitandukanye bya mashini.Ingano yubugari bwihuza nayo izagira ingaruka kubushobozi bwo gutwara iminyururu.Ubushobozi n'ubuzima bwa serivisi.
