Kuzungulira mkombero wosalala - mphamvu ya mavuto ozungulira ndi mayankho

1. Galimoto yolemera makilogalamu 2000 imazungulira curve pamsewu wathyathyathya wa radius 150 m. Coefficient of static friction ndi 0.5. Dziwani liwiro lalikulu kuti galimotoyo itsatire curve ndipo isagwedezeke. Kuthamanga chifukwa cha mphamvu yokoka = 10 m/s ².

Zodziwika:

Kulemera (m) = 2000 kg

Ulalo wozungulira (r) = mamita 150

Koyefifiti ya kukangana kosasinthasintha ( μs ₎ = 0.5

Kulemera (w) = mg = (2000 kg)(10 m/s ² ) = 20,000 kg m/s ² = 20,000 N

Mphamvu ya kukangana kosasunthika (F _s ) = μ _s N = μ _s w = (0.7) (20,000 N) = 14,000 N
