Sebatang alumunium (alpha= 0,000024/derajat C) pada suhu 0 derajat C, mempunyai panjang 10 m. jika dipanaskan hingga suhu 100 derajat C , berapa panjang alumunium sekarang ?

Lt = Lo ( 1 + α Δt ) = 10 ( 1 + 0,000024 x 100 ) = 10 ( 1 + 0,0024 ) = 10 x 1,0024 = 10,024 meter

Diketahui = Lo = 10 m Δt = 100 - 0 = 100'C α = 0,000024/'C Ditanya = Lt..? Jawab = Lt = Lo ( 1 + α Δt ) = 10 ( 1 + 0,000024 x 100 ) = 10 ( 1 + 0,0024 ) = 10 x 1,0024 = 10,024 meter
= 10 ( 1 + 0,000024 x 100 )
= 10 ( 1 + 0,0024 )
= 10 x 1,0024
= 10,024 meter
Δt = 100 - 0 = 100'C
α = 0,000024/'C
Ditanya = Lt..?
Jawab = Lt = Lo ( 1 + α Δt )
= 10 ( 1 + 0,000024 x 100 )
= 10 ( 1 + 0,0024 )
= 10 x 1,0024
= 10,024 meter
