Question on: JAMB Physics - 1992
A bridge made of steel is 600m long. What is the daily variation in its length if the night-time and daytime temperatures are 10oC and 35oC respectively. The linear expansivity of steel is 0.000012C-1
A
0.18cm
B
1.80cm
C
18.00cm
D
1800cm
Ask EduPadi AI for a detailed answer
Correct Option: A
(\alpha) = (\frac{extension}{L\Delta\theta})
0.000012 = (\frac{e}{600 \times (35 - 10})
= 0.18cm
