Maka,
ὼ ~ 1/T Atau ὼ ~ f atau ὼ ~ n/t
ὼx : ὼy = nx ty : ny ty
ὼx : ὼy = (10) (30) : (60) (20)
ὼx : ὼy = 3 : 12
ὼx : ὼy = 1 : 4
f = n/t
ω = 2πf
f₁ = n/t
= 10/30
= 0,333 Hz
ω₁ = 2πf₁
= 2 x π x 0,33
= 0,66π rad/s
f₂ = n/t
= 60/20
= 3 Hz
ω₂ = 2πf₂
= 2 x π x 3
= 6π rad/s
ω₁ : ω₂ = 0,66π : 6π
= 0,66 : 6
= 1 : 9
Jadi, perbandingankecepatan sudut roda x dan roda y adalah 1 : 9
