Mienzaniso yemibvunzo pamusoro pekukurumidzira kwekona uye kukurumidza kwetangential

4 Mienzaniso yemibvunzo yekumhanyisa kwekona uye yekumhanyisa kwetangential

1. Vhiri rine radius ye30 cm rinotenderera nekumhanya kwakasimba kwe5 rad/s²Kumhanya kwetangential kwenzvimbo iri (a) 10 cm kubva pa ekseli (b) 20 cm kubva pa ekseli (c) pamucheto wevhiri kwakakura sei?
Kukurukurirana

2. Kana kumhanyisa kwenzvimbo iri pamucheto wepropeller ine radius ye50 cm kuri 2 m/s², chii chinonzi angular acceleration yepropeller?
Kukurukurirana
Zvinozivikanwa :
Nharaunda (r) = 50 cm = 0,5 metres
Kukurumidza kweTangential (a_kusviba) = 2 m/s²
Akabvunzwa : kumhanyisa kwekona kwepropeller
Jawab :

3. Vhiri rine radius ye 20 cm iro pakutanga rakamira rinokurumidziswa zvakaenzana. Mushure memasekonzi maviri, vhiri rinotenderera nekumhanya kwe angle ye 10 rad/s. Sarudza hukuru hwekukurumidzisa kwe tangential kwe (a) poindi 10 cm kubva pa ekseli (b) kumucheto kwevhiri!
Kukurukurirana

Akabvunzwa : kumhanyisa kwetangential (a) pa r = 0,1 metres (b) pa r = 0,2 metres
Jawab :
Kutanga verenga kumhanyisa kwevhiri kwekona. Shandisa fomura yekufamba kwedenderedzwa yakakurumidza zvakaenzana nhamba 1:

4. Propeller ine radius ye20 cm, iyo inotanga kutenderera nekumhanya kwe angle ye 20 rad/s, inomira kutenderera mushure memasekonzi maviri. Tsvaga hukuru hwekumhanya kwe tangential kwe (a) poindi 10 cm kubva pa axis (b) kumucheto kwepropeller!
