Ezikhathini zanamuhla, izinto ezihlanganisiwe eziphezulu ziye zasetshenziswa ezindizeni zomphakathi wonke umuntu azisebenzisayo ukuqinisekisa ukusebenza kahle kwendiza kanye nokuphepha okwanele. Kodwa uma sibheka emuva emlandweni wonke wokuthuthukiswa kwezindiza, yiziphi izinto ezazisetshenziswa endizeni yokuqala? Ngokombono wokuhlangabezana nezici zendiza yesikhathi eside kanye nomthwalo owanele, izinto ezisetshenziselwa ukukhiqiza indiza kumele zibe lula futhi ziqine. Ngesikhathi esifanayo, kumele kube lula ngabantu ukuguqula nokucubungula, futhi bahlangabezane nezidingo eziningi ezifana nokumelana nokushisa okuphezulu kanye nokumelana nokugqwala. Kubonakala sengathi ukukhetha izinto ezifanele zezindiza akuyona into elula.
Ngokuthuthuka okuqhubekayo kwesayensi yezinto zezindiza, abantu baqala ukusebenzisa izinto ezihlanganisiwe eziningi, besebenzisa izinto ezimbili noma ngaphezulu ezihlanganisiwe, behlanganisa izinzuzo zezinto ezahlukene, kodwa futhi beqeda nobunzima bazo. Ngokungafani nezinsimbi zendabuko, izinto ezihlanganisiwe ezisetshenziswa ezindizeni eminyakeni yamuva nje zisebenzise kakhulu i-resin matrix elula exutshwe ne-carbon fiber noma izingxenye ze-glass fiber. Uma kuqhathaniswa nezinsimbi, zilula kakhulu ukuguqulwa nokucutshungulwa, futhi amandla ezingxenye ezahlukene anganqunywa ngokwemidwebo yomklamo. Enye inzuzo ukuthi zishibhile kunezinsimbi. Indiza yabagibeli i-Boeing 787, eye yaduma kakhulu emakethe yezindiza zomphakathi yomhlaba wonke, isebenzisa izinto ezihlanganisiwe ngezinga elikhulu.
Akungabazeki ukuthi izinto ezihlanganisiwe ziyisiqondiso esiyinhloko socwaningo emkhakheni wesayensi yezinto zezindiza esikhathini esizayo. Ukuhlanganiswa kwezinto eziningana kuzodala umphumela wento eyodwa kanye nenye enkulu kunezimbili. Uma kuqhathaniswa nezinto zendabuko, kunamathuba amaningi. Izindiza zabagibeli zesikhathi esizayo, kanye nemicibisholo eyinkimbinkimbi kakhulu, amarokhethi, kanye nezindiza zasemkhathini nezinye izimoto zasemkhathini, zonke zinezidingo eziphakeme zokuzivumelanisa nezimo kanye nokusungula izinto ezintsha. Ngaleso sikhathi, izinto ezihlanganisiwe kuphela ezazingenza umsebenzi. Kodwa-ke, izinto zendabuko ngokuqinisekile ngeke zisuke esigabeni somlando ngokushesha kangaka, futhi zinezinzuzo ezingatholakali ezintweni ezihlanganisiwe. Ngisho noma u-50% wendiza yabagibeli yamanje yenziwe ngezinto ezihlanganisiwe, ingxenye esele isadinga izinto zendabuko.
