Jika, m1 = 1 kg, m2 = 2 kg dan m3 = 3kg.
Diketahui :
m1 = 1 kg
m2 = 2 kg
m3 = 3 kg
Ditanya :
Jawab :
jarak m2 ke poros P, r2 = 1 m
jarak m3 ke poros P, r3 = 2 m
sehingga momen inersia sistem,
I = ∑ m × r²
I = m2 × r2² + m3 × r3²
I = 2 × 1² + 3 × 2²
I = 2 × 1 + 3 × 4
I = 2 + 12
I = 14 kgm²
jarak m1 ke poros Q, r1 = 1 m
jarak m3 ke poros Q, r3 = 1 m
I = m1 × r1² + m3 × r3²
I = 1 × 1² + 3 × 1²
I = 1 × 1 + 3 × 1
I = 1 + 3
I = 4 kgm²
