Izibonelo ezi-5 zesivinini se-angular kanye nemibuzo yesivinini se-tangential
1. Ibhola liboshelwe entanjeni ende engamamitha amabili bese lijikeleziswa ngendilinga evundlile kuze kube yilapho ibhola lihamba ngesivinini esingaguquki sama-radians ayi-10/umzuzwana. Thola ubukhulu bejubane le-tangential lephuzu elingu-(a) amamitha angu-0,5 ukusuka ku-axis (b) imitha eli-1 ukusuka ku-axis (c) onqenqemeni lwesondo.

Ubude bentambo = irediyasi yendlela eyindilinga (r) = amamitha ama-2
Ijubane le-angular = ama-radian ayi-10/isekhondi
Kubuziwe : ijubane eliqondile lephuzu ku-(a) r = 0,5 amamitha (b) r = 1 imitha (c) r = 2 amamitha
Jawab :
Ifomula yobudlelwano phakathi kwesivinini se-tangential kanye nesivinini se-angular:
(A) Ijubane eliqondile (v) lephuzu ku-r = amamitha angu-0,5
v = (amamitha angu-0,5)(10 rad/s) = amamitha angu-5/sekondi
(B) Ijubane eliqondile (v) lephuzu ku-r = amamitha angu-1
v = (amamitha angu-1)(10 rad/s) = amamitha angu-10/sekondi
(C) Ijubane eliqondile (v) lephuzu ku-r = amamitha angu-2
v = (amamitha angu-2)(10 rad/s) = amamitha angu-20/sekondi
2. Imvamisa yokujikeleza kwepropeller engu-20 cm ububanzi ingu-5000 rpm. Thola ijubane eliqondile lephuzu elingu-(a) 5 cm ukusuka ku-axis (b) 10 cm ukusuka ku-axis noma emaphethelweni epropeller.

3. Iphuzu eliseceleni kwesondo elinobubanzi obungamasentimitha angu-30 lihamba ngendilinga ngesivinini samamitha ayi-10/ngomzuzwana. Liyini ijubane lesondo eliyi-angular?
Ingxoxo
I-Diketahui :
Irediyasi (r) = 30 cm = 0,3 amamitha
Ijubane le-Tangential (v) = amamitha ayi-10/umzuzwana
Kubuziwe : ijubane le-angular?
Jawab :
4. Imoto ihamba amamitha ayi-10 njalo ngomzuzwana owodwa. Uma ububanzi bamasondo emoto bungama-50 cm, thola isivinini se-angle samasondo!
Ingxoxo
I-Diketahui :
Irediyasi yesondo (r) = amamitha angu-0,25
Isivinini somphetho wesondo (v) = amamitha ayi-10/umzuzwana
Kubuziwe : ijubane lesondo eliyi-angular!
Jawab :
5. Uma ijubane lesondo elinobubanzi obungu-20 cm lingu-120 rpm, imoto izohamba ibanga elingakanani uma ihamba imizuzwana eyi-10?
Ingxoxo
I-Diketahui :
Irediyasi yesondo (r) = 20 cm = 0,2 amamitha
Ijubane lesondo eliyi-angular = imijikelezo engu-120 / imizuzwana engu-60 = imijikelezo emi-2 / isekhondi = (2)(6,28) ama-radian / isekhondi = ama-radian angu-12,56 / isekhondi
Kubuziwe : ibanga elihanjwe yimoto ngemizuzwana eyi-10.
Jawab :
Isivinini somphetho wesondo:
Ijubane lomphetho wesondo elingamamitha angu-2,5 ngomzuzwana lisho ukuthi iphuzu eliseceleni kwesondo lihamba ngamamitha angu-2,5 njalo ngomzuzwana. Ngemva kwemizuzwana eyi-10, iphuzu eliseceleni kwesondo selihambe ngamamitha angu-25.
Ngakho ibanga elihanjwa yimoto ngemizuzwana eyi-10 lingamamitha angama-25.
