Hobaneng ha matsoao a moepa a bontša liphesente le seo a se bolelang

Mokhanni e mong le e mong bonyane hanngoe phihlelong ea hae ea ho khanna o ile a khanna sebakeng se maralla. Litheohelang le metheong li etelloa pele ke matšoao a nang le khutlotharo e ntšo e bontšang peresente. Liphesente tsee li bolela eng hona hobaneng li bontšoa?

Liphesente li bolela eng

Ho matsoao a meepa le meepa, peresente e bontša tangent ea angle ea tšekamelo. Haeba u sheba tsela ho tloha lehlakoreng 'me u nahana hore ke khutlo-tharo e nepahetseng - tsela ka boeona ke hypotenuse, moeli oa horizon ke leoto le haufi,' me bophahamo ba ho theoha ke leoto le fapaneng, joale tangent ke karolelano ea bophahamo ba ho hloa kapa ho theohela molaneng. Ka mantsoe a mang, liphesente li bonts'a phetoho boemong bo otlolohileng ba tsela ka limithara tse fetang lekholo la limithara.

Hobaneng ho sebelisoa liphesente

Ts'ebetsong ea sephethephethe sa litsela, angle ea tšekamelo ka likhato e ke ke ea bolella mokhanni letho. ’Me palo ea liphesente e bontša hore na koloi e tla theoha kapa e nyolohe hakae limithara tse ling le tse ling tse 100, ke hore, haeba letšoao le le 12%, le bolela ho nyoloha kapa ho theoha ka limithara tse 12 ka limithara tse ling le tse ling tse 100.

Ntlha ea bobeli ea boiketlo ba ho bonts'a sekhahla sa tšekamelo e le peresente ke hore tangent ea eona e lekana le coefficient ea ho khomarela lebili la koloi tseleng. Ka lebaka la sena, hoa khoneha ho bala lebelo leo u ka nyolohelang ho lona kapa ho theoha ntle le ho fofa ho tloha tseleng.

Mokhoa oa ho fetolela liphesente ho li-degree

O ka fetola sekhutlo se sekameng ho tloha ho liperesente ho ea ho likhato ho calculator fonong ea hau ka ho e fetolela ho "mokhoa oa boenjiniere". Nomoro ea likhato e tla ba boleng ba arc tangent ea peresente e bontšitsoeng letšoao la tsela.

Ke hobane'ng ha mokhanni a hloka ho tseba boleng bo nepahetseng ba moepa oa ho nyoloha kapa ho theoha

Ho itšetlehile ka maemo a leholimo, ho ts'oaroa ha mabili a nang le tsela e tla fapana. Ehlile mokhanni e mong le e mong o ile a khanna ka leqhoa, le pula, le lehloeng, a utloa phapang ena. Lisupa tse nang le thaere e theohang kapa e nyolohang sebakeng seo moepa o atamelang 10%. Haeba nakong ea lipula ho phahama ho fokotsa lebelo, joale bonyane koloi e ke ke ea phahama.

Ho phaella moo, metseng ea khale e lebōpong la leoatle ho na le literata tseo ho tsona lehlakoreng la tšekamelo le fetang mefuta eohle ea litekanyetso. Ke hore, ha u khanna letsoapong la sekontiri se metsi se nang le coefficient ea angular ea 20%, katleho ea braking e theoha ka halofo.

Ka hona, ke habohlokoa ho ela hloko matšoao a ho phahama le ho theoha, haholo-holo maemong a leholimo a mabe. Ho tseba coefficient ea ho khomarela mabili ka tsela, ho itšetlehile ka maemo a leholimo le boemo ba tšekamelo, e ka ba ea pholosa bophelo maemong a mang.
