Amandla omlilo

Amandla okuxhatshazwa yinkqubo apho imizimba isebenzisana xa ihamba isondelelana. Oku kungabikho ukufuduka, ukunyakaza komzimba kwisiqhelo samanzi okanye segesi. Kukho igama lezesayense le ngxaki - ukusebenzisana. Njengomthetho, ukufundiswa kwenkqubo yokukhathala kubhekisana ne-physics, icandelo elithi "iMicchanical of interaction frictional", kwaye kwezinye iimeko - i-tribology.

Amandla okuxhatshazwa yinto yombane, kodwa kuphela phantsi kwesimo esisodwa - into enjalo kwiimeko eziqhelekileyo.

Ngokuphathelele iintlobo zale ngxaki, ngoko, phambi kwenkqubo yokunyuka kwemizimba, inamandla ephuma ekusebenzisaneni kwayo ingahlulwa:

- Slip friction, oku kungamandla ayenzeka xa ukunyakaza kokuguqulela komzimba omnye kunxulumene nomnye. Isebenza emzimbeni onikeziwe kwindlela echasene nesikhokelo slip ngokwayo.

- Ukuqhaqha okanye ukutshatyalaza. Ivela xa enye yezinto ezimbini ezinxulumene nazo zihamba ngokuxhomekeke kwenye.

- I-Friction yokuphumla yindlela enokuthi ivele phakathi kwamalungu amabini adibeneyo, ngandlela-nye okanye enye, kwaye ikhusela ukubonakala kwenkqubela. Njengomthetho, kwenzeka ngeentambo ezincinci okanye uqhagamshelwano lwemizimba. Izenzo kwindlela echasene nentshukumo ehambelanayo.

Ngokuphathelele i-physics ngokwayo, amandla okubambisana kunye nokusebenzisana kwahlula phakathi:

- Dry, xa kukho ubudlelwane obuqilileyo, kwaye abahlulelwanga naliphi na iiblue lubricants. Le meko ayifani ngokuqhelekileyo ekusebenzeni kwaye inempawu ezahlukileyo-ubukho be-index ephezulu yokuxhatshazwa kwamandla.

- Ulungelelaniso - oku kufikelele kwindawo yokudibanisa kukho iindawo, kunye nemimandla eyahlukileyo. Ukunyanelana kwamandla kwendalo kukugqithiseleyo.

- Ukuxutywa - ngale nkqubo, indawo yokudibanisa iqulethe iindawo ezithile zombini kunye nokuxubana komile. Iyakwenzeka kwimeko xa izidumbu zibhaptizwa kumanzi, kuphela kulo mzekelo amandla okubambisana aya kubonakala ngezinga le viscosity of medium.

- Elastohydrodynamic - kwenzeka xa ukuxubana kwangaphakathi kunye nezinto ezenza imisebenzi yokucoca kubaluleke kakhulu. Njengomthetho, kwenzeka xa isantya sohambelane sentshukumo sanda kakhulu.

Kubalulekile ukuba siqaphele ukuba ngenxa yokuxakeka kweenkqubo ze-physicochemical ezihambelana nale nzeka ngexesha lokusebenzisana, ukunyanzeliswa kwezi nkqubo eziphunyezwayo akukwazi ukuchazwa ngendlela yendlela yokwenza i-classic mechanics.

Ukuphendula umbuzo woluphi uhlobo lokuxhatshaza oluxhomekeke kuyo, sinokuthi kusinikwe amandla oxinzelelo kunye ne- coefficient of friction. Isalathisi sokugqibela sixhomekeke kwizinto ezininzi: kwinqanaba lokuhlanzeka okubhekiselwe kuyo indawo ethile, ngohlobo lwezinto ezivela kuyo imizimba ngokwayo, kwaye ukuba kukho ukukhawuleza, kweso sahluko. Kubalulekile ukwazi ukuba amandla okuxhatshaza ayenzeki ngokuxhomekeke kwingingqi apho izidumbu zidibanisa khona.

Ekupheliseni, sinokuthi ukubonakala kobambiswano oluthile kwenza kube lula ukuhamba ngaphaya komhlaba. Ngokomzekelo, kwinkqubo yokuhamba, ukuxhaswa komgangatho kunye neyodwa yenzeke, echanekileyo ngenxa yokungqubuzana. Njengomphumo woqhagamshelwano, i-sole iyayiphula phantsi kwaye umntu uya phambili.

Ngendlela efanayo, ukuqoqwa kwamavili kwithuthi kusetyenziswa indlela. Kukuphucula nokwandisa le nto iqhutywe ngamathayi amatsha kunye namathayi, kwaye ukukhwela imoto kunokufakela "iphiko", elixinezela imoto kwimizila.
