Posankha njira yopangira ulusi, zinthu monga kukula kwa ulusi, zofunikira zolondola, katundu wakuthupi, kuchuluka kwa kupanga, ndi kulingalira mtengo ziyenera kuganiziridwa.
Mbiri
Mawu achingerezi ofanana ndi screw ndi Screw.Tanthauzo la mawuwa lasintha kwambiri m’zaka mazana aposachedwapa.Osachepera mu 1725, amatanthauza "mating".
Kugwiritsiridwa ntchito kwa mfundo ya ulusi kungayambikenso ku chida chonyamulira madzi chozungulira chomwe chinapangidwa ndi katswiri wachi Greek Archimedes mu 220 BC.
M’zaka za m’ma 400 AD, maiko a m’mphepete mwa Nyanja ya Mediterranean anayamba kugwiritsa ntchito mfundo ya ma bolts ndi mtedza ku makina osindikizira omwe amagwiritsidwa ntchito popangira vinyo.Panthawiyo, ulusi wakunja unkakulungidwa ndi chingwe ku cylindrical bar, ndiyeno amalembedwa motsatira chizindikiro ichi, pamene ulusi wamkati nthawi zambiri unkapangidwa ndi kumenyetsa kuzungulira ulusi wakunja ndi zipangizo zofewa.
Cha m'ma 1500, pachithunzi cha chipangizo chopangira ulusi chojambulidwa ndi Leonardo da Vinci waku Italiya, panali kale lingaliro logwiritsa ntchito screw yachikazi ndi zida zosinthira kukonza ulusi wamitundu yosiyanasiyana.Kuyambira pamenepo, njira yodulira ulusi mwa makina yayambika m’makampani opanga mawotchi ku Ulaya.
Mu 1760, abale a ku Britain J. Wyatt ndi W. Wyatt anapeza chilolezo chodulira zitsulo zamatabwa pogwiritsa ntchito chipangizo chapadera.Mu 1778, British J. Ramsden nthawi ina anapanga chipangizo chodulira ulusi choyendetsedwa ndi nyongolotsi, zomwe zimatha kupanga ulusi wautali molunjika kwambiri.Mu 1797, British H. Mozley anagwiritsa ntchito screw lead yachikazi ndi zida zosinthira kutembenuza ulusi wachitsulo ndi maphikidwe osiyanasiyana pa lathe yomwe iye adakonza, ndikukhazikitsa njira yosinthira ulusi.
M'zaka za m'ma 1820, Maudsley anapanga gulu loyamba la matepi ndipo amafa pokonza ulusi.
Kumayambiriro kwa zaka za m'ma 1900, chitukuko cha makampani opanga magalimoto chinalimbikitsanso kukhazikika kwa ulusi ndi chitukuko cha njira zosiyanasiyana zolondola komanso zogwira mtima.Mitundu yosiyanasiyana ya mitu yotsegulira yokha ndi matepi ocheperako okha adapangidwa motsatizana, ndipo mphero ya ulusi idayamba kugwiritsidwa ntchito.
Kumayambiriro kwa zaka za m'ma 1930, ulusi ukupera udawonekera.
Ngakhale ukadaulo wogubuduza ulusi unali wovomerezeka koyambirira kwa zaka za zana la 19, chifukwa cha zovuta kupanga nkhungu, chitukukocho chinali chochepa kwambiri.Sizinali mpaka Nkhondo Yachiwiri Yapadziko Lonse (1942-1945) kuti chifukwa cha zosowa za kupanga zida zankhondo ndi chitukuko cha ukadaulo wogaya ulusi, vutoli linathetsedwa.Vuto lolondola la kupanga nkhungu lapeza chitukuko chofulumira.
