Fungura amateka y'akagari

Leonardo Da Vinci yakoresheje imyanya ya Calibrated counterwight kuri lever ya mashini kugirango aringanize kandi amenye uburemere butazwi. Guhindura ibishushanyo bye yakoresheje levers nyinshi, buri burebure butandukanye kandi buringaniye hamwe nuburemere bumwe busanzwe. Mbere ya hydraulic na elegitoroniki ya gare yipakurura ingirabuzimafatizo zasimbuye imashini zikoreshwa mu gupima inganda, iyi minzani ya mashini yakoreshejwe cyane. Byakoreshejwe gupima ibintu byose kuva ibinini kugeza kumodoka ya gari ya moshi kandi babikoze neza kandi byizewe mugihe byahinduwe neza kandi bikabungabungwa. Barimo gukoresha uburyo bwo kuringaniza ibiro cyangwa gutahura imbaraga zakozwe na mashini. Ibyuma bya gage byambere, byabanjirije imbaraga zirimo hydraulic na pneumatic.

Mu 1843, umuhanga mu bya fiziki w’Ubwongereza Charles Wheatstone yateguye uruziga rw’ikiraro rushobora gupima amashanyarazi. Ikiraro cya Wheatstone ni cyiza cyo gupima impinduka zo guhangana zibaho muri gage. Nubwo gage ya mbere irwanya insinga ya gage yakozwe mu myaka ya za 1940, ni bwo ibikoresho bya elegitoroniki bigezweho byafashwe ni bwo ikoranabuhanga rishya ryashobokaga mu buhanga no mu bukungu. Kuva icyo gihe, icyakora, gage zinini zagiye ziyongera haba nkibipimo byubunini bwa mashini ndetse no muri selile yonyine. Uyu munsi, usibye laboratoire zimwe na zimwe zikoreshwa mu buringanire bwa tekinike, ingirabuzimafatizo ya gage yiganje mu nganda zipima. Ingirabuzimafatizo ya pneumatike ikoreshwa rimwe na rimwe aho hifuzwa umutekano w’imbere n’isuku, kandi selile hydraulic selile zifatwa ahantu kure, kuko zidasaba amashanyarazi. Strain gage imitwaro itanga ibisobanuro kuva kuri 0.03% kugeza 0.25% byuzuye kandi birakwiriye mubikorwa byose byinganda.
