Inyungu Nkuru y'Inyigisho y'Ikivange c'Ingano Zitatu-

Igikoresho gikoreshwa n’umugozi mukuru, igihimba c’umubiri c’ico gikoresho gifise ibipimo bitatu-kigenda gisubiramwo, nk’uguhindura, guhindukiza no gutera, ivyo bikaba bituma ico kintu kigenda mu nzira zitatu kijanye n’umubiri woroshe. Ivyo bituma ibikoresho bitandukanye bigendana, bikakwiragizwa, bikarundanywa, bikavangirana, ivyo bikaba bituma bivangirana mu buryo bumwe. Ni vyiza cane mu guvanga ibikoresho vy’amafu n’ivy’ubutare mu buryo bumwe cane mu bikorwa vy’imiti, imiti, ibifungurwa, inganda zitoyi, ubuhinga bwa none, imashini, ubucukuzi bw’amabuye y’agaciro n’ivyuma, uburinzi bw’igihugu, n’ibigo bitandukanye vy’ubushakashatsi.

Ico gikoresho co guvanga inyigisho c’ingero zitatu-kibereye guvanga amafu canke utugingo ngengabuzima dufise ubushobozi bwo gutemba neza kandi gikoreshwa cane mu bikorwa vy’imiti, imiti, ibifungurwa, ivyuma, inganda zidakomeye, n’inganda zikora ubushakashatsi mu vya siyansi. Kubera ko iyo cylindre y’uguvanga ifise ibikorwa vy’inzira nyinshi-, yihutisha uruja n’uruza n’ugukwiragira kw’ibikoresho bitandukanye mu gihe c’uguvanga, igakingira ugutandukanya n’ukwirundanira kw’ibikoresho bitewe n’inguvu zikwegera hasi ziterwa n’inkomezi z’uguhunga mu bivanga muri rusangi, gutyo bikaba bituma habaho ukuvanga neza cane. Irafise kandi igikoresho co gupima umubiri -ubwoko bw'ugutanga ivyiyumviro. Ikindi kandi, ubushobozi bwo gutwara ibintu burengeye ubw’ikivunji c’inyigisho c’ingero zitatu-burengeye incuro zibiri ubw’ibivunji bisanzwe.

Uburyo bwo gutwara umuvumba w’ibipimo bitatu-bugizwe na moteri, uburyo bwo kugabanya umuvuduko, igihindura incuro, n’uburyo bwo kugenzura. Ivyo bikoresho vyoroshe, kandi uburyo bwo gutanga amakuru buraryoshe kandi bwizigirwa. Igihindura incuro gishobora gukingira neza inertia y’umuzigo uremereye-ugutangura no guhitamwo neza ikibanza ciza c’ibarabara ry’ibifungurwa iyo imashini ihagaze, bikaba vyorosha kugaburira canke gusohora.
