Ubuciko bokudala i-boomerangs isakhiwo sobudala sasendulo. Esikhathini esidlule eChina, le mikhiqizo endizayo ebheka izindiza yaba izikhali, ngakho insimbi noma izinkuni zazisetshenziselwa ukuzenza. Nokho, umlando walolu hlobo lwezikhali waqala ngisho nangaphambili. Aborigines ase-Australia, abazingela izinyoni, baqaphela ukuthi ezinye izinti zinyuka, kanti abanye ngandlela-thile babuyela ezandleni zabo. Kungaba yinto engavamile uma impahla enjalo ye-aerodynamic eshiywe ngaphandle kokunakekelwa, ngoba ukuzingela ngesikhali sokuziphendulela kwakulula kakhulu.
Namuhla i-boomerang ekhangayo emangalisa i-toy enhle kakhulu yezingane. Ezitolo lapho amaqembu ahlukene emikhiqizo yezingane athengiswa khona, ngokuvamile umuntu angabona ama-boomerang enziwe ngepulasitiki ngemibala ehlukahlukene. Amathoyizi anjalo ayabizi, kepha ukudala i-boomerang ngokwabo ngeke kuthathe isikhathi esiningi ekhaya. Ngaphezu kwalokho, ingane izothakazelisa kakhulu ukudlala i-boomerang, ekudalweni kwakhe.
Iphepha noma amakhadibhodi - yilokho okudingayo kulabo abangakwazi ukwenza i-boomerang ngezandla zabo ngemizuzu embalwa. Le toyidla evusa amadlingozi ithandwa kakhulu nezingane, futhi ngisho nabazali bazo, kuyathakazelisa kakhulu ukubukela indiza yakhe bese ubuya. Ungakwazi ngisho nokuhlela ukuncintisana okumnandi ukuphonsa endlini noma emgwaqweni. Konke lokhu kuzotholakala kulabo abafunda isihloko sethu sendlela yokwenza izandla zabo zephepha noma i-boomerang yamaphephabhuku.
Ngakho-ke, ngaphambi kokwenza i-boomerang yephepha, lungisa iphepha le-A4 elidinga ukunqunyulwa. Sidinga ingxenye eyodwa kuphela.
- Chaza ukugoba kwe-axis enezingqimba. Sisebenzisa izingxenye ezingezansi nezingezansi zeshidi kuwo. Khona-ke wonke umsebenzi wobuciko kufanele uboshwe, kodwa usuvele uhamba nge-axis eqondile. Endaweni lapho izingxenyana ziboshwe khona, zibophe emgqeni ophakathi. Manje siqondisa izingqungquthela kanye nomdwebo, evula ingxenye engezansi yomsebenzi wethu.
- Gcwalisa imininingwane emigqeni ye-diagonal esiyifinyelele phakathi, ukugoqa ungqimba olungezansi ngakwesokudla enkabeni. Ingxenye yesobunxele iphakanyiswa engeni ye-degrees angu 90 kuya endizeni, iyijika ngokuhamba kwewashi.
- Faka ku-line ye-axis isigamu seshidi, futhi ingxenye egobile inciphisa phansi ukuze uthole i-angle engakwesokudla. Siphonsa ingqimba engenhla yesigxobo esingaphezulu se-boomerang. Esikhathini esikhwameni esakhiwa phakathi, sigcwalisa ingxenyeni engqimba engxenyeni engezansi, engaphambi kokugoba, ukufakwa kuhlanganisiwe. Ingxenye ephakathi manje isiqinisekisiwe ngokuqinile.
- Sifaka amafolda ekugcineni kwephepha eliphansi lephepha. Gcwalisa izingalo ngaphakathi bese uqondisa ukufaka. Ngemva kwalokho sibeka ikhoneni elingakwesokunxele ngaphakathi kwengxenye, kuqala ukuyigoqa. Kwafakwa umphongolo emsebenzini wokusebenza. Manje bhonqa ikhoneni lesokudla.
- Sigcwalisa umgomo ohlosiwe owenziwe emgodini, owenziwe nge-valve efakwe ngaphakathi. Sithola isigxobo se-boomerang nge-cut even. Ngokufanayo, sivula ama-corn angaphezulu kwe-ray. Manje iphepha lethu le-boomerang elenziwe ngezandla lilungele ukushayela!

Manje uyazi ukuthi ungenza kanjani i-boomerang yephepha, kodwa ukwehluleka kwayo kungukuthi fragility. Isitokisi esenziwe ngamakhadibhodi sizoba namandla kakhulu. I-Boomerang ingenziwa ngamacu amathathu, amane namahlanu. Ngokwecebo elingezansi, lihlala nje kuphela ukuze likhishwe emakhadibhodi aminyene inani elidingekile lezingxenye bese ubamba iqhwa. Lokhu kubalulekile, ngoba kubalulekile ukucabangela ukumelana nomoya.
Ngaphezu kwalokho, ama-angles phakathi kwawo wonke ama-boomerang kufanele abe okufanayo, ngoba ithoyizi egijima ngeke ibuyele. Ungahlola lokhu nge-protractor evamile.
