Ingcindezi ukudla okuqinile ngokwemvelo

okuqinile isimo ingcindezi - ngokuyinhloko abakhi lokuqala isitha. Ngenxa yokuthi kukhona ingcindezi kwezinto eziqinile, akunakwenzeka ukuba sifeze ezinye amaphrojekthi isimiso. Ngokuthakazelisayo, lasendulo, kunalokho bajabulela le ndawo, esikhiqiza wakha izakhiwo ezinkulu ezibabazekayo. Pyramids nezinye izikhumbuzo eziningi izakhiwo - konke lokhu kuyizinto imiphumela umsebenzi onzima ekudaleni yobuciko omangalisayo. Cabanga ukuthi ezifana ingcindezi isihlobo ukuba ukudla okuqinile.

Found Ngisho nangalezo zikhathi ingcindezi kwezinto eziqinile ifomula inikeza:

P = F / S,

okusho ibutho esebenza phezu okuyisihloko ingcindezi.

Kufanele kuqashelwe ukuthi eqinisweni, ukucindezela amandla ka umzimba uhlale omuhle futhi isebenza zombili izinkomba. Lapha usebenza umthetho Newton kuqala - amandla isinyathelo elilingana nebutho ukumelana naye. Kusebenza ekuphileni - ukucindezela kwendikimba isisindo isakhiwo, ukuthi kuyoba izingqimba aphansi kanye isisekelo okufanayo. Ngakho-ke, abaklami, abakhi sihlale silindele Will isisekelo isakhiwo. Yiqiniso, lokhu ukubala kuhlanganisa nezinye izinto (emoyeni force -. Kusukela ophahleni, amanzi angaphansi komhlaba, umsebenzi zokuzamazama komhlaba nokunye).

Kungani ngidinga umuntu ukuhlakaza isisindo sakho phezu kwamanzi emikhulu? Bese ucabanga inaliti noma bakugwaze. Bobabili has a ebukhali ingxenye engcono Ukungena khono. Manje khumbulani skiing kanye ithrekhi-uhlobo tractor. Skiers musa ukuwela iqhwa, kanye nogandaganda kukhona cross ezinhle ngokusebenzisa emaxhaphozini, njengoba babe endaweni enkulu contact - a imbeddability ezincane. Lokhu ubonisa ifomula eziyisisekelo ekhombisa ingcindezi ukudla okuqinile - ngamandla efanayo, kodwa ezindaweni ezahlukene, ingcindezi zizohluka. Kuyinto inhlukanozigaba esikweleni. okungukuthi elikhulu endaweni, aba maningi ingcindezi. Futhi okuphambene nalokho.

Manje emuva abakhi. Bakwenzelani bacindezele - ikhanda elikhulu? Zonke ndaba endaweni efanayo. Phela, impahla, eliqinile, ngakho-ke kunzima. Cabanga esindayo ukhonkolo slabs-ukugqagqana. Yiqiniso, esikhathini sethu, kukhona okuningi eqinile, izinto engasindi. Kodwa akukhona konke lula. Noma yimuphi umsebenzi wokwakha Kulinganiselwa nenzuzo. Futhi uma intengo enjalo super-izinto uphakeme, nezilinganiso ukwakhiwa izindleko zizoba ezinkulu. Ngenxa yalokho, ikhasimende akusho ukudonsa kwi ezezimali noma iphrojekthi kuyovuzwa isikhathi eside. Kodwa sishilo ngenhla, ukuthi abantu basendulo basebenzisa ingcindezi kwezinto eziqinile ukuze zihambelane nabo.

Ngalezo zinsuku, zokwakha ziziphilela kulinganiselwe ezihlukahlukene futhi eziningi. Phela, embonini yezimayini yayingekho, futhi itshe eliqoshwe ngesandla. ukhonkolo noma nosimende waba futhi uthayiphe izakhi elihlangana. Kwakufanele sisetshenziswe esikhundleni ukubanjwa ukudla okuqinile ingcindezi. Iqiniso liwukuthi enkulu ingcindezi, aba maningi amandla adingekayo izinto. Kodwa ngakolunye uhlangothi, lokhu webutho elikhulu kokukhuhlana. Futhi, eyaziwa kungenza umehluko omkhulu. Ngenxa yalokho, sithola ukuthi ihadiwe akudingekanga, konke waphumula amandla adonsela phansi futhi ibutho kokukhuhlana.

Manje cabanga ukuthi ingcindezi kakhulu has a isitimela ku komzila - 300000 KPA !!! At ingcindezi ezikhethekile abakhasi ugandaganda - 20 KPA. Izimo zethu zihluke kakhulu Iphuzu elithakazelisayo lelo, kubonakala, ababhema ixhaphozi ugandaganda, kudala uma kuqhathaniswa ingcindezi ongaphakeme emhlabathini. Lokhu kuvumela ukuba ahambe emhlabeni ukuvimbela kanye Marshland ngenxa ithrekhi ebanzi. Uma sikhuluma ukungqubuzana oshiwo ngenhla, kungaba ezinhlobo ezahlukene futhi enikezwa:

F = μ × N, [H]

lapho F - amandla kokukhuhlana [N]

μ - ngomshikisho Coefficient

N - evamile yokusabela [H].

Amandla ingcindezi njengoba kungabonwa, has kokubili amaphuzu emihle nemibi. Nature ingashintshwa ukuze lesi simo. Abantu abavela ukwakhiwa Ngokuhlakanipha elula iyiswe kokusungulwa izinto ezintsha kanye nobuchwepheshe. Okunjalo ngumkhuba nemvelo futhi kuye esinamandla.
