Amaduka yose agurisha ibintu agomba kuyatangaza, birakenewe, ariko tugomba gucira imanza ingingo nyinshi zamamaza.Kurugero, poropagande izwi cyane "guhagarika urugi" bivuze ko hashize igihe kitari siyansi.Mubisanzwe iyo tuvuze ibyerekeye imodoka, urugi rwumuryango rusohoka akenshi kugirango tugire icyo tuvuga kubice, iki kintu gito kigomba kuvuga, ariko kugirango tubone kuvuga, ntigishobora kuvuga kigoramye.
Hariho ubwoko bubiri bwibice bihuza umuryango numubiri, kimwe cyitwa hinge, ikindi cyitwa limiter, nkuko izina ribigaragaza, kimwe gikosowe, ikindi ni ukugabanya Inguni yugurura umuryango, reka duhere kuri hinge .Hinge bakunze kuvuga ko ari hinge, hariho uburyo bubiri busanzwe kumasoko kurubu, kashe na casting, imideli myinshi yubudage yerekana imiterere ya hinge.Kuberako igishushanyo mbonera gitandukanye, kubwibyo byubwoko bubiri bwibikoresho bya hinge ntabwo ari bimwe, impeta zipanze zikunda kuba ndende cyane kuruta impeta zashyizweho kashe.
Hinges zifite ibyiza byo gukora neza nubumwe, muri make, biroroshye kandi binini, uhereye kumiterere yubushobozi bwo gutwara nabyo bifite ibyiza, ariko uburemere ni bunini, igiciro cyumusaruro kizaba kinini;Igiciro cyo gutanga umusaruro ugereranije na kashe ya kashe kizaba gito, kandi ntihazabaho kugabanuka gukoresha imodoka zumuryango, zishobora kuzuza ibisabwa.
