Moment of Inertia & Rotational Energy

I = mr², KE = ½Iω², τ = Iα

Keterangan:

  • I
    Moment of inertia (kg·m²)
  • m
    Mass (kg)
  • r
    Radius (m)
  • ω
    Angular velocity (rad/s)
  • α
    Angular acceleration (rad/s²)

Contoh Perhitungan

Momen Inersia Titik

Soal:

m=2kg, r=0.5m. Cari I?

Penyelesaian:
  1. 1.I = 2 × 0.5²
  2. 2.I = 0.5 kg·m²
Hasil:I = 0.5 kg·m²

Momen inersia benda titik is 0.5 kg·m².
