Ikigo cyibicuruzwa

Abantu bose bazi ko moteri ari umutima wimodoka, kandi amavuta ni maraso yimodoka. Kandi urabizi? Hariho kandi igice cyingenzi cyimodoka, nicyo cyungurura ikirere. Akayunguruzo ko mu kirere akenshi birengagizwa n'abashoferi, ariko icyo buri wese atazi nuko ari agace gato cyane kagira akamaro cyane. Gukoresha akayunguruzo keza ko mu kirere bizongera ibinyabiziga bikoresha lisansi, bitume imodoka itanga imyanda ikomeye ya karubone, isenya metero y’ikirere, imyuka ya karubone ikabije, nibindi. Turabizi ko gutwika lisansi cyangwa mazutu muri moteri ya moteri isaba guhumeka umwuka mwinshi. Mu kirere hari umukungugu mwinshi. Igice kinini cyumukungugu ni dioxyde ya silicon (SiO2), nikintu gikomeye kandi kidashonga, aricyo kirahure, ububumbyi, na kristu. Igice cyingenzi cyicyuma kirakomeye kuruta icyuma. Niba yinjiye muri moteri, bizongera imyambarire ya silinderi. Mubihe bikomeye, bizatwika amavuta ya moteri, bikubite silinderi kandi bitere urusaku rudasanzwe, kandi amaherezo bizatera moteri ivugururwa. Kubwibyo, kugirango wirinde ko umukungugu winjira muri moteri, hashyirwaho akayunguruzo ko mu kirere kinjira mu muyoboro wa moteri.
