Izibonelo zemibuzo mayelana nokusheshisa kwe-angular kanye nokusheshisa kwe-tangential

4 Izibonelo zemibuzo yokusheshisa okune-angular kanye nokusheshisa okune-tangential

1. Isondo elinobubanzi obungu-30 cm lijikeleza ngokusheshisa okungaguquki kwe-angle okungu-5 rad/s². Kukhulu kangakanani ukusheshisa kwe-tangential kwephuzu elingu-(a) 10 cm ukusuka ku-axle (b) 20 cm ukusuka ku-axle (c) onqenqemeni lwesondo?

2. Uma ukusheshisa okuqondile kwephuzu eliseceleni kwepropeller elinobubanzi obungu-50 cm kungu-2 m/s², iyini i-angular acceleration ye-propeller?
Ingxoxo
I-Diketahui :
Irediyasi (r) = 50 cm = 0,5 amamitha
Ukusheshisa kwe-tangential (a_tan) = 2 m/s²
Kubuziwe : ukusheshisa kwe-angular kwe-propeller
Jawab :

3. Isondo elinobubanzi obungu-20 cm eliqale liphumule lisheshiswa ngokulinganayo. Ngemva kwemizuzwana emi-2, isondo lijikeleza ngesivinini esijikelezayo esingu-10 rad/s. Thola ubukhulu bokusheshiswa okuqondile (a) iphuzu elingu-10 cm ukusuka ku-axle (b) onqenqemeni lwesondo!
Ingxoxo

Kubuziwe : ukusheshisa okubonakalayo (a) ku-r = 0,1 amamitha (b) ku-r = 0,2 amamitha
Jawab :
Okokuqala bala ukusheshisa kwesondo okugobile. Sebenzisa ifomula yokunyakaza okujikelezayo eshintsha ngokulinganayo inombolo 1:

4. I-propeller ene-radius engu-20 cm, eqala ukujikeleza ngesivinini esijikelezayo esingu-20 rad/s, iyayeka ukujikeleza ngemva kwemizuzwana emi-2. Thola ubukhulu bokusheshisa kwe-tangential (a) iphuzu elingu-10 cm ukusuka ku-axis (b) emaphethelweni e-propeller!
