Kungani izimpawu zokwehla nokwenyuka zikhombisa amaphesenti nokuthi zisho ukuthini

Umshayeli ngamunye okungenani kanye okuhlangenwe nakho kwakhe kokushayela washayela endaweni enamagquma. Ukwehla nokwenyuka okuyizintaba kwandulelwa izimpawu ezinonxantathu omnyama ezibonisa iphesenti. Asho ukuthini la maphesenti futhi kungani ekhonjiswa?

Asho ukuthini amaphesenti

Ezimpawini zokwehla nokwenyuka okungummango, iphesenti libonisa i-tangent ye-engeli yokuthamba. Uma ubheka umgwaqo ohlangothini futhi ucabange njengonxantathu ongakwesokudla - umgwaqo ngokwawo yi-hypotenuse, umugqa womkhathizwe ungumlenze oseduze, futhi ukuphakama kokwehla kungumlenze ophambene, khona-ke i-tangent isilinganiso ukuphakama kokukhuphuka noma ukwehla kumugqa womkhathizwe. Ngamanye amazwi, amaphesenti abonisa ushintsho ezingeni eliqondile lomgwaqo ngamamitha ngaphezu kwesigaba samamitha ayikhulu.

Kungani kusetshenziswa amaphesenti

Enqubeni yethrafikhi yomgwaqo, i-angle yokuthambekela ngamadigri ngeke itshele umshayeli lutho. Futhi isibalo samaphesenti sikhomba ukuthi imoto izokwehla noma ikhuphuke kangakanani njalo ngemva kwamamitha angu-100, okungukuthi, uma uphawu luwu-12%, kusho ukwenyuka noma ukwehla ngamamitha angu-12 njalo ngamamitha angu-100.

Iphuzu lesibili lokulula ekuboniseni i-angle yokuthambekela njengephesenti ukuthi i-tangent yayo ilingana ne-coefficient yokunamathela kwesondo lemoto endaweni yomgwaqo. Ngenxa yalokhu, kungenzeka ukubala isivinini ongakhuphuka ngaso umqansa noma wehle ngaphandle kokundiza usuka ethrekhi.

Ungawaguqula kanjani amaphesenti abe amadigri

Ungakwazi ukuguqula i-engeli yokutsheka isuke kumaphesenti iye kumadigri emshini wokubala ocingweni lwakho ngokuyishintshela "kumodi yobunjiniyela". Inombolo yamadigri kuzoba inani le-arc tangent yephesenti elivezwe ophawini lomgwaqo.

Kungani umshayeli edinga ukwazi inani eliqondile lomqansa wokukhuphuka noma ukwehla

Kuye ngezimo zezulu, ukubamba kwamasondo ngomgwaqo womgwaqo kuzohluka. Impela wonke umshayeli wayeshayela eqhweni, emvuleni, naseqhweni, ezwa lo mehluko. Izikhombisi ezinethaya elehlayo noma elenyukayo endaweni lapho umthambeka usondela ku-10%. Uma esimweni sezulu semvula ekukhuphukeni kokunciphisa, okungenani imoto ngeke ivuke.

Ngaphezu kwalokho, emadolobheni amadala asogwini kunemigwaqo lapho i-angle yokuthambekela idlula zonke izinhlobo zezindinganiso. Okusho ukuthi, lapho ushayela emthambekeni we-asphalt emanzi ene-angular coefficient engu-20%, ukusebenza kahle kwamabhuleki kwehla ngesigamu.

Ngakho-ke, kubalulekile ukunaka izimpawu zokukhuphuka nokwehla, ikakhulukazi esimweni sezulu esibi. Ukwazi i-coefficient yokunamathela kwamasondo ngomgwaqo, kuye ngezimo zezulu kanye ne-angle yokuthambekela, kungasindisa ukuphila kwezinye izimo.
