Munyika yeinjiniya yemotokari, vanozvininipisavhiri-lug-nutuyevhiri regumbo bhaudhi kutamba mabasa akakosha mukuona kuchengetedzwa uye kuvimbika kwemotokari dzedu. Izvi zvisingatarisirwi zvikamu zvingaita sezvisina basa pakutanga, asi ndiwo magamba asina kusimba anobata mavhiri edu akachengeteka uye anobvumira kutasva kwakatsetseka uye kwakachengeteka.
Gumbo-lug-nut, chisungiso chidiki, chine shinda chinowanzo gadzirwa nesimbi kana zvimwe zvinhu zvakasimba, chakagadzirirwa kusungirira vhiri kuhubhu yemotokari. Basa rayo rekutanga kugadzira kubatana kwakasimba uye kwakachengeteka pakati pevhiri uye hub, kudzivirira chero kusada kuzunguzika kana mafambiro panguva yekutyaira. Magadzirirwo ayo akangwara, anowanzo kuve ane hexagonal kana octagonal chimiro, anogonesa kugadzika nekubvisa zviri nyore, kuita shanduko yetai uye kugadzirisa basa rakati chechetere.
Nekune rimwe divi, vhiri regumbo bhaudhi ndiyo imwe mhando yekusimbisa iyo inoshanda zvakafanana neiyo lug nut asi ine chimiro chakasiyana. Panzvimbo yekuve chidimbu chakaparadzana, bhaudhi itsvimbo imwe ine shinda ine musoro wakatenderedzwa. Iyo inopinza zvakananga mukati mehubhu yevhiri uye inobuda mukati mevhiri, ichibvumira kusungirirwa kwakachengeteka kwevhiri. Kazhinji inoshandiswa pamwe chete nevhiri hub nzungu, bhaudhi rinopa imwe sarudzo yekuisa, kunyanya inofarirwa nevamwe vagadziri vemotokari.
Ose ari maviri vhiri-lug-nut uye vhiri lug bolt anoedzwa zvakasimba kuti asangane neakasimba kuchengetedza zviyero. Vanofanira kutsungirira masimba makuru, akadai sehuremu hwemotokari, kukurumidza kukurumidza, kubhureki kamwe kamwe, uye kushata kwemigwagwa. Mainjiniya vanoverenga zvine hungwaru iwo akakwana torque maratidziro ezvitsigiro izvi kuti ave nechokwadi chekuti mavhiri akachengetedzwa zvakaringana uku achidzivirira kuomesa zvakanyanya izvo zvinogona kukonzera kukuvara.
Kugara uchigadzirisa uye kuongororwa kwezvikamu izvi zvinoita sezvisingatarisike kwakakosha kuti uve nechokwadi chekuvimbika kwavo. Mechanics anotarisa zviratidzo zvekusakara, kuora, kana deformation, sezvo yakasakara kana kukuvadzwa vhiri-lug-nuts kana mabhaudhi emakumbo anogona kukanganisa kugadzikana kwekusangana kwevhiri, zvichitungamira kune njodzi dzinogona kuitika mumugwagwa.
Saka, nguva inotevera yauchapinda munzira wotanga rwendo, tora nguva yekutenda kuvimbika uye kukosha kwezvinhu izvi zvidiki asi zvine simba - vhiri-lug-nut uye vhiri lug bolt - kushanda nesimba kuchengetedza mavhiri ako achifamba zvakachengeteka. uye zvakanaka munzira yakarongwa.
