koefisien muai panjang, α = 1,2*10⁻⁵/K
suhu awal, T₁ = 10°C
suhu akhir, T₂ = 110°C
ΔT = 110 - 10 = 100°C
ΔT kelvin = ΔT celcius
ΔT = 100 Kelvin
Panjang akhir, L₂ = ?
L₂ = L₁ * (1 + α * ΔT)
L₂ = 1 * (1 + 1,2*10⁻⁵ * 100) = 1,0012 m
T₂ = 110°C
L₁ = 1 m
α = 1,2 x 10⁻⁵/K
T₁ = 10°C
ΔT = 110 - 10 = 100°C = 100 K
Dit :
L₂.....?
Dij :
L₂ = L₁ x ( 1 + α x ΔT )
L₂ = 1 x ( 1 + 1,2 x 10⁻⁵ x 100)
L₂ = 1,0012 m
Semoga membantu
