• momen inersia
r = roda, b = bola
Roda
mr = 1 kg
Rr = 30 cm
Ir = ½ mr Rr²
Bola
mb = 1,5 kg
Rb = 8 cm
Ib = (2/5) mb Rb²
Perbandingan
Ib / Ir = [(2/5) mb Rb²] / [½ mr Rr²]
Ib / Ir = (4/5) • (mb / mr) • (Rb / Rr)²
Ib / Ir = (4/5) • (1,5 / 1) • (8 / 30)²
Ib / Ir = (4/5) • (3/2) • (16/225)
Ib / Ir = 32/375 = 32 : 375 ← jwb
Ok ?
