khohlano
"Khohlano" e bolela ho hanyetsa motsamao pakeng tsa bokaholimo ba ho kopana ha lintho tse peli ka motsamao o lekanyelitsoeng. Boholo ba matla a khohlano (F) bo lekana le sehlahisoa sa coefficient ea khohlano (μ) le khatello e otlolohileng (N) holim'a matla a khohlano, e hlalositsoeng ke foromo ea 'mele: F=μN. Bakeng sa sistimi ea brake: (μ) e bolela coefficient ea khohlano pakeng tsa pad ea brake le disc ea brake, 'me N ke Matla a Pedal a sebelisoang ke piston ea caliper ea brake holim'a pad ea brake. Ha coefficient ea khohlano e hlahisoa ke khohlano e kholo, khohlano e kholo, empa coefficient ea khohlano pakeng tsa pad ea brake le disc e tla fetoha ka lebaka la mocheso o phahameng o hlahisoang ke khohlano, ke hore, coefficient ea khohlano (μ) e fetoloa ka mocheso, mofuta o mong le o mong oa pad ea brake ka lebaka la thepa e fapaneng le curve e fapaneng ea coefficient ea khohlano, kahoo li-pad tsa brake tse fapaneng li tla ba le mocheso o fapaneng o sebetsang, 'Me mocheso o sebetsang o sebetsang, sena ke seo motho e mong le e mong a lokelang ho se tseba ha a reka li-pad tsa brake.
