Jawaban:
α = 9x10⁻⁶ ⁰C
L = 2 m
T = 20 ⁰C
Ta = 40 ⁰C
ΔT = 40-20 = 20 ⁰C
La = ? (panjang pada suhu 40 ⁰C)
La = L + ΔL
La = L + LαΔT
La = 20 + 2 x 9x10⁻⁶ x 20 = 20,00036 m
mungkin yg ditanya ΔL (pertambahan panjan)
maka,
ΔL = 0,00036 m = 0,36 mm = 0,4 mm
*maaf bila tak benar
*biasakan cari jawaban lain utk dibandingkan
Penjelasan:
" Life is not a problem to be solved but a reality to be experienced! "
