Kutenderedza denderedzwa rakatsetseka - mashandiro ematambudziko ekufamba kwedenderedzwa uye mhinduro

1. Mota inorema 2000 kg inotenderera mugwagwa wakatsetseka we radius 150 m. Iyo coefficient ye kukweshana kwemamiriro ezvinhu i0.5. Sarudza kumhanya kwakanyanya kuitira kuti mota itevere curve uye isatsvedzerere. Kuwedzera nekuda kwegiravhiti = 10 m/s².

Zvinozivikanwa:

Misa (m) = 2000 kg

Nharaunda (r) = 150 mamita

Kukweshana kwekusagadzikana (coefficient of static friction)μ_s= = 0.5

uremu (w) = mg = (2000 kg)(10 m/s²) = 20,000 kg m/s² = 20,000N

Simba rekukweshana kwakasimba (F)_s) = μ_s N = μ_s w = (0.7)(20,000 N) = 14,000 N

1. Huremu nehuremu
2. simba remazuva ose
3. Mutemo wechipiri wekufamba waNewton
4. Simba rekukakavadzana
5. Kufamba pamusoro penzvimbo yakatwasuka pasina simba rekukweshana
6. Kufamba kwemiviri miviri ine kumhanyisa kwakafanana pamusoro penzvimbo yakatwasuka ine simba rekukweshana
7. Kufamba mundege yakakotama pasina simba rekukweshana
8. Kufamba mundege yakakombama nesimba rekukweshana
9. Kufamba muelevator
10. Kufamba kwemiviri kwakabatana netambo nemapulley
11. Miviri miviri ine hukuru hwakafanana hwekukurumidzira
12. Kutenderedza denderedzwa rakati sandara - simba rekufamba kwedenderedzwa
13. Kutenderera curve yakakomberedzwa - simba rekufamba kwedenderedzwa
14. Kufamba kwakafanana mudenderedzwa rakatwasuka
15. Simba repakati nepakati rakafanana mukufamba kwedenderedzwa
