Zozungulira-zozungulira mutu ndi zida zofunika kwambiri pazida zakunja, zomangira nangula, kapena zothandizira pakanthawi kochepa. Kusankha kwawo zinthu kumakhudza mwachindunji chitetezo, kulimba, komanso kusinthasintha kwa chilengedwe. Kusankha zinthu zasayansi kumafuna kuganizira mozama za makina, mmene chilengedwe chilili, komanso mtengo-wogwira ntchito.
Kugwiritsiridwa Ntchito Kwakukulu kwa Zida Zachitsulo
Chitsulo chosapanga dzimbiri ndicho kusankha kokonda zomangira-zozungulira{1}}zapamwamba kwambiri. Kukaniza kwake bwino kwa dzimbiri (makamaka mndandanda wa 304/316) kumapangitsa kuti ikhale yoyenera malo okhala ndi mchere wambiri komanso chinyezi, monga misasa ya m'mphepete mwa nyanja kapena malo amankhwala. Zomangira zachitsulo za carbon zitha kusinthidwa bwino popaka galvanizing kapena kupopera mbewu mankhwalawa, kuwongolera kwambiri kukana dzimbiri. Kulimba kwawo komanso kukwera mtengo kwake-kumakhala kothandiza kumawapangitsa kukhala osavuta kugwiritsa ntchito pazinthu zambiri, koma amafunikira kuwasamalira pafupipafupi kuti apewe dzimbiri. Aluminiyamu aloyi ndi yopepuka komanso yosachita dzimbiri, -yosamva, kupangitsa kuti ikhale yoyenera kuteteza katundu{10}}zida zovutirapo zokwera mapiri. Komabe, mphamvu zake zochepa zimalepheretsa kugwiritsidwa ntchito kwake mu nthaka yolimba kapena mphepo yamphamvu.
Ntchito Yowonjezera ya -Zopanda Zitsulo
Mainjiniya a pulasitiki apansi panthaka (monga glass fiber reinforced nayiloni) amapambana kwambiri m'malo oundana ndi chipale chofewa kapena m'malo ochitira masewera a ana chifukwa chopepuka,{0}}sakuwongolera, komanso kuzizira{1}}kusungunuka kwawo. Komabe, katundu wawo-ndi wofooka, zomwe zimawapangitsa kukhala oyenera kumangogwiritsa ntchito{4}}zovuta zochepa. Ma spikes apansi ophatikizika, pophatikiza ulusi ndi utomoni, amawonetsa kuthekera kolinganiza mphamvu ndi kulemera kwake ndipo pakadali pano amagwiritsidwa ntchito makamaka pazida zapanja zaukatswiri-.
Zosankha Zosankha
Ogwiritsa ntchito asankhe zinthu zoyenera potengera kuuma kwa dothi, nyengo, ndi zofunikira pakugwiritsa ntchito kwawo. Pogwiritsa ntchito-kunja kwa nthawi yaitali, zitsulo zosapanga dzimbiri kapena zitsulo za kaboni zokutidwa ndizomwe zimakonda; Pazofunikira kwakanthawi kopepuka, aluminium alloy kapena pulasitiki angagwiritsidwe ntchito. Kusankha zinthu sikumangokhudza magwiridwe antchito komanso kumathandizira kwambiri pakuwongolera ngozi. Kulephera kwa magwiridwe antchito chifukwa chochepetsa mtengo kuyenera kupewedwa.
