Ibikoresho byose mubikorwa byo kongera cyangwa guhora imbaraga ziva hanze amaherezo bizarenga imipaka runaka kandi birimburwe. Hariho ubwoko bwinshi bwimbaraga zo hanze zitera kwangiza ibikoresho, nka tension, igitutu, kogosha, na torsion. Imbaraga zombi, imbaraga zingana nimbaraga zitanga umusaruro, ni imbaraga zingutu gusa.
Izi mbaraga zombi ziboneka binyuze mubizamini bya tensile. Ibikoresho bikomeza kuramburwa ku gipimo cyagenwe cyo gupakira kugeza igihe kimenetse, kandi imbaraga ntarengwa yitwaza iyo ivunitse ni umutwaro uremereye wibintu. Umutwaro uremereye ni uburyo bwo kwerekana imbaraga, kandi igice ni Newton (N). Kuberako Newton nigice gito, mubihe byinshi, kilonewtons (KN) irakoreshwa, kandi umutwaro uremereye ugabanijwe nicyitegererezo. Guhangayikishwa bivuye kumwanya wambere wambukiranya igice byitwa tensile strength.
Irerekana ubushobozi ntarengwa bwibikoresho byo kunanirwa kunanirwa. None imbaraga zo gutanga ni iki? Imbaraga zitanga umusaruro ni ibikoresho bya elastique gusa, ibikoresho bidakomeye nta mbaraga zitanga. Kurugero, ubwoko bwose bwibikoresho byibyuma, plastiki, reberi, nibindi, byose bifite elastique kandi bitanga imbaraga. Ikirahure, ububumbyi, ububaji, nibindi muri rusange ntabwo byoroshye, kandi niyo ibikoresho nkibi byoroshye, ni bike. Ibikoresho bya elastique bikoreshwa muburyo buhoraho kandi bukomeza kwiyongera imbaraga ziva hanze kugeza zimenetse.
Ni iki cyahindutse rwose? Ubwa mbere, ibikoresho bigenda bihindagurika muburyo bukoreshwa nimbaraga ziva hanze, ni ukuvuga, ibikoresho bizasubira mubunini bwabyo nuburyo byifashe nyuma yimbaraga zo hanze zavanyweho. Iyo imbaraga zo hanze zikomeje kwiyongera no kugera ku gaciro runaka, ibikoresho bizinjira mugihe cyo guhindura ibintu. Iyo ibikoresho bimaze kwinjizwa muburyo bwa plastike, ingano yumwimerere nuburyo bwibikoresho ntibishobora kugarurwa mugihe imbaraga zo hanze zavanyweho! Imbaraga zingingo zingenzi zitera ubu bwoko bubiri bwo guhindura ibintu nimbaraga zumusaruro wibintu. Bihuye nimbaraga zikoreshwa, imbaraga zingirakamaro ziyi ngingo ikomeye yitwa umusaruro.
