Isosiyete yacu iherutse kohereza abakiriya ubwoko bw'udupira tw'ubwiza buhanitse, kandi twishimiye gutangaza ko buri dupira twabitswe neza kandi twageragejwe mu kigo cyacu cy’umwuga cyo kubika no gupima udupira tw’ubwiza i Shanghai.

Ibikoresho byo gupima ibyuma bigira uruhare runini mu gukora no kubungabunga ibyuma bifata amapine. Ibi bikoresho byagenewe gupima ibipimo bitandukanye by'ibyuma bifata amapine kugira ngo birebe ko ari byiza, imikorere n'ukuri.

Ibyuma bihuza ibyuma ni ingenzi mu nganda zitandukanye zirimo ibikoresho by'imashini, iby'indege n'iby'imodoka. Ibi bikoresho bihuza ibyuma bikoreshwa mu gutwara imizigo ishingiye ku mirasire n'imirongo, ibi bikaba ari ingenzi mu gukoresha umuvuduko mwinshi no mu buryo bunoze.

Gupima ibyuma bipima: ibintu by'ingenzi n'uburyo bwo kubipima Gusuzuma ibyuma bipima ni inzira y'ingenzi mu gukora ibyuma bipima no kugenzura ubuziranenge.

Itandukaniro rikomeye riri hagati y'udupira tw'insinga na Uburyo bwo guterura umupiras ni ubwoko n'imiterere y'ibintu bizunguruka bakoresha.

Ubushinwa ni kimwe mu bihugu byavumbuye ibyuma bizunguruka kera ku isi, kandi imiterere y'ibyuma bizunguruka yanditswe mu bitabo bya kera by'Abashinwa. Ukurikije ibyavuye mu bushakashatsi bw'ibyataburuwe mu matongo n'amakuru, icyuma cya kera cyane mu Bushinwa gifite igishushanyo mbonera cy'imiterere ya none yo guzunguruka cyagaragaye mu myaka ya 221-207 mbere ya Yesu (Qin Dynasty) mu Mudugudu wa Xuejiaya, Akarere ka Yongji, Intara ya Shanxi.

Umubumbe w'uruziga icyuma gifata imizingas ni ingenzi mu bikorwa bitandukanye by’inganda, cyane cyane mu mashini ziremereye aho ubushobozi bwo gutwara imizigo myinshi n’ubushobozi bwo kwihuza ari ingenzi cyane. Izi bearing zagenewe gutwara imizigo iremereye mu cyerekezo kimwe kandi zishobora kwihanganira imizigo minini ya radial, bigatuma ziba amahitamo menshi kandi yizewe mu bihe bigoye byo gukora.
