Ngubengi kurva datar – dinamika masalah lan solusi gerakan bunder

1. A 2000-kg car rounds a curve on a flat road of radius 150 m. The coefficient of gesekan statis is 0.5. Determine the maximum speed so the car follows the curve and not skid. Akselerasi amarga gravitasi = 10 m/s2.

Dikenal:

Massa (m) = 2000 kg

Radius (r) = 150 meter

Coefficient of static friction (μs) = 0.5

bobot (w) = mg = (2000 kg)(10 m/s)2) = 20,000 kg m/s2 = 20,000 N

Force of static friction (Fs) = μs N = μs w = (0.7)(20,000 N) = 14,000 N
