Komanso phunzirani zitsanzo za liwiro la tangential ndi liwiro la angular.
Ngati chinthu chizungulira mozungulira wotchi ndikumaliza kuzungulira kamodzi (360o) mu sekondi imodzi, ndiye kuti liwiro la angular la magawo onse a fan ndi 1 rotation/second = 360 o /second = 6,28 radians/second ndipo malangizo a angular velocity ndi otchinga. Ngati radius ya fan ndi 20 cm, m'mphepete mwa fan mumayenda mozungulira ndi liwiro la (2)(3,14)(20 cm) / sekondi imodzi = 125,6 cm/s = 1,256 m/s. Mfundo 1 cm (0,01 m) kuchokera ku axis imayenda mozungulira ndi liwiro la (2)(3,14)(1 cm) / sekondi imodzi = 6,28 cm/s = 0,0628 m/s. R yaying'ono, liwiro limakhala laling'ono. Mu kuyenda kozungulira , liwiro nthawi zambiri limatchedwa tangential speed. Limatchedwa tangential chifukwa malangizo a liwiro nthawi zonse amakhala tangential ku njira yozungulira.
Ubale pakati pa liwiro ndi liwiro la angular umafotokozedwa kudzera mu equation:
Chitsanzo cha mavuto.
1. Kukula kwa liwiro la angular Chida chachiwiri ndi ma radians 6,28 pa mphindi. Kodi ndi angati liwilo lalikulu mfundo yomwe ili pa 2 cm kuchokera ku axis?
