Fiziki ya Mpira wa Roulette

Mpira

Kale unali wa minyanga ya njovu, kenako ivorine (celluloid), tsopano kawirikawiri Teflon kapena polima yofanana, 18 mpaka 21 mm, magalamu ochepa. Makasino amasunga makulidwe angapo ndi kuwasinthasintha, chifukwa mpirazipangizoMpiraMpira waung’ono umene umaponyedwa mu njira motsutsana ndi rotor. Mipira yamakono ndi ya ivorine kapena Teflon, 18–21 mm.Werengani yonse → waung’ono ndi wopepuka umadumpha kwambiri pa ma fretzipangizoFretChogawa chachitsulo pakati pa tibowo tiwiri pa gudumu.Werengani yonse → ndi kumwazika kwambiri, zimene ndi zabwino kwa kasino. Mpira uyenera kukhala wosakopeka ndi maginito ndipo umayang’aniridwa ngati uli wozungulira bwino; mpira wosazungulira bwino umagwa msanga ndi mosadziwika.

Pa njira

Pa njira yozungulira yopendekeka mpira umafunika mphamvu ya centripetal mv²/r kuti upitirize kuzungulira. Khoma la njira limaipereka pamene mpira uli wothamanga. Pamene mpira ukuchepa liwiro, mphamvu yofunikira imatsika mpaka gawo la mphamvu yokoka lolowera mkati motsatira kupendekeka lipitirira zimene kapangidwe kangasunge, ndipo mpira umagwa. Liwiro lofunika kwambiri limadalira utali ndi ngodya ya njira yokha, choncho pa gudumu linalake liwiro pogwa limakhala pafupifupi losasintha kuchokera kuzungulira kupita kuzungulira, kawirikawiri 1 mpaka 1.3 m/s.

Kalembedwe ka kuchepa kwa liwiro

Kukangana pozungulira kumachotsa mphamvu pa mlingo pafupifupi wosasintha; kukankha kwa mpweya kumachotsa zambiri pamene mpira uli wothamanga. Pamodzi zimapangitsa kuzungulira kulikonse kukhala kotalikirapo pang’ono kuposa komaliza ndi kuwonjezeka kodziwikiratu. Kuyeza nthawi za mazungulidwe awiri kapena atatu otsatizana kumakuthandizani kupeza manambala a kukangana ndi kukankha kwa mpweya ndi kuyerekeza kuzungulira kumene mpira udzagwa. Pa gudumu loyera kuyerekeza kumeneku n’kolondola mpaka magawo ochepa a khumi a sekondi; izi ndi zimene olosera oyeza nthawi amayeza, ndipo tsamba la Kuchepa kwa Liwiro limaonetsa masamu ake.

Kumwazika

Kumwazika kumayezedwa pa gudumu lililonse ngati kagawidwe ka kabowo komaliza poyerekeza ndi kabowo kali pansi pa malo ogwera; pa magudumu amakono kawirikawiri kumafika tibowo 10 mpaka 15 mbali iliyonse, ndipo magudumu ena amaonetsa ma mode awiri kapena atatu chifukwa ma deflector ena amagundidwa kawirikawiri.

Tanthauzo lake kwa wosewera

Chilichonse mpaka kugwa chingathe kudziwika m’mfundo koma n’chopanda ntchito kwenikweni popanda zipangizo ndi mabetcha ochedwa. Chilichonse pambuyo pa kugwa chinapangidwa kuti chisadziwike. Zotsatira zake ndi masewera amene zotsatira zake ndi zachisawawa osati chifukwa fiziki ndi yachisawawa koma chifukwa chidziwitso chofunikira kuzilosera chimawonongedwa pakati pa njira ndi kabowo.
