Ada yng ngerti pemuaian? Tolong dong

Dik : Lo = 50 cm
delta T = T2 - T1 = 40 - 10 = 30 oC
a = 25 x 10^-6 /oC
Dit : a. Delta L .....?
b. Lakhir ...?

a. Delta L = Lo . a . delta T
Delta L = (50) . (25x10^-6) . (30)
Delta L = 0,0375 cm

b. Delta L = Lakhir - Lo
Lakhir = Delta L + Lo
Lakhir = 0,0375 + 50
Lakhir = 50,0375 cm
