Ifiziksi yebhola ye-roulette

Ibhola encinci kumzila omile njengekhoni, ibanjwe phezulu sisantya sodwa.

Impendulo emfutshane

Ibhola ye-roulette ihlala emzileni ngelixa amandla afunekayo ukuba ijikeleze anikwa kukuthambeka komzila. Xa icotha ngaphantsi kwesantya esithile, iqengqeleka yehle kwi-apron, ibethe isiphambukisi, isasazeke.

Ibhola

Kudala yayiyimpondo yendlovu, emva koko i-ivorine (uhlobo lwe-celluloid), ngoku idla ngokuba yi-Teflon okanye ipolima efanayo, ububanzi bayo buyi-18 ukuya kwi-21 mm, ubunzima bayo ziigram ezimbalwa. Iikhasino zigcina ubukhulu obuninzi kwaye ziyazitshintsha, kuba ibholaizixhoboIbholaIbhola encinci ephoswa emzileni ngokuchasene nerotha. Iibhola zanamhlanje zenziwe nge-ivorine okanye nge-Teflon, zi-18–21 mm.Funda yonke → encinci nelula itsiba ngakumbi kwizahluliizixhoboIsahluliIsahluli sentsimbi phakathi kwezikhewu ezimbini evilini.Funda yonke → kwaye isasazeke ngokubanzi ngakumbi, nto leyo ilungele ikhasino. Ibhola kufuneka ingabi namagnethi kwaye ihlolwa ukuba ingqukuva na; ibhola engangqukuvanga iwa kwangoko nangendlela engaqhelekanga.

Emzileni

Kumzila ongqukuva othambekileyo, ibhola idinga amandla e-centripetal mv²/r ukuze iqhubeke ijikeleza. Udonga lomzila luwanika ngelixa ibhola ikhawuleza. Xa ibhola icotha, amandla afunekayo ayehla de inxalenye yomxhuzulane etsalela ngaphakathi kwithambeka idlule oko ukwakheka kunokukubamba, ize ibhola iqengqeleke iphume. Isantya esibalulekileyo sixhomekeke kuphela kwiradiyasi nakwi-engile yomzila, ngoko kwivili elithile isantya sokuwa siphantse singatshintshi ukusuka kumjikelo ukuya kumjikelo, ngokwesiqhelo si-1 ukuya ku-1.3 m/s.

Ukucotha emzileni kuphantse kube ngu v′ = −(a + b·v): ixesha lokuxubuxubana elingatshintshiyo kunye nexesha lokuxhathisa komoya elihambelana nesantya.

Indlela yokucotha

Ukuxubuxubana xa iqengqeleka kususa amandla ngezinga eliphantse lingatshintshi; ukuxhathisa komoya kususa ngakumbi xa ibhola ikhawuleza. Zombini zenza ukujikeleza ngakunye kube kude kancinci kunokwangaphambili ngesixa esiqikelelekayo. Ukulinganisa amaxesha okujikeleza amabini okanye amathathu alandelelanayo kukuvumela ukuba ufumane izibalo zokuxubuxubana nokuxhathisa komoya, uqikelele ukuba ibhola iza kuwa kokuphi ukujikeleza. Kwivili elicocekileyo uqikelelo luchanekile ukuya kwiinxalenye ezimbalwa zeshumi zomzuzwana; yile nto ilinganiswa ngabaqikeleli abasebenzisa ixesha, kwaye iphepha lokucotha libonisa izibalo.

Ukusasazeka

Kwakhona: slot, cup.Funda yonke → sokuwa” okanye kwikota yevili kude. Emva koko itsiba phezu kwezahluli, ngamanye amaxesha iphinde itsibe iphume esikhewini esele ingene kuso. Ukusasazeka kulinganiswa kwivili ngalinye njengonikezelo lwesikhewu sokugqibela xa sithelekiswa nesikhewu esingaphantsi kwendawo yokuwa; kumavili anamhlanje ngokwesiqhelo kufikelela kwizikhewu eziyi-10 ukuya kwi-15 kwicala ngalinye, kwaye amanye amavili abonisa iincopho ezimbini okanye ezintathu kuba iziphambukisi ezithile zibethwa rhoqo ngakumbi.

Imilo eqanjiweyo kodwa eqhelekileyo. Unikezelo lwenyani lulinganiswa kwivili ngalinye, kwibhola nganye, kulwalathiso ngalunye, kwaye luyatshintsha ngokuguga.

Oku kuthetha ukuthini kumdlali

Yonke into ukuya ekuweni inokwaziwa ngokwethiyori kodwa ayincedi nto ngokwenyani ngaphandle kwezixhobo neebheji ezenziwa emva kwexesha. Yonke into emva kokuwa yenzelwe ukuba ingaziwa. Isiphumo ngumdlalo iziphumo zawo zingaqikelelekiyo hayi kuba ifiziksi ingaqikeleleki, kodwa kuba ulwazi olufunekayo ukuziqikelela lutshatyalaliswa phakathi komzila nesikhewu.

Imibuzo

Ngaba ibhola enzima itshintsha ii-odds?

Hayi ii-odds. Itshintsha ukusasazeka: iibhola ezinzima zitsiba kancinci kwaye zizinza kwangoko.

Kutheni iikhasino zitshintsha iibhola?

Ukoyisa nabani na olungelelanise isiqikeleli kwibhola enye, nangenxa yokuba iibhola ziyaguga.

Ngaba ibhola ingaphuma evilini?

Kunqabile, xa iphoswe ngamandla okanye umzila uphelile. Umjikelo uyarhoxiswa.

Uncumo

Ibanjwe phezulu sisantya. Yehliswa kukuxubuxubana. Isasazwa ngabom.
