The Eiffel tower, which is made of steel (coefficient of linear expansion 13 x 10^-6/ degree C.), is 320 m high at 20(Degrees C). the change in height of the tower between the winter months when the average temperature is -20C and the summer months when the average temperature is 35C is ?
a. 42 cm
b. 35 cm
c. 23cm
d. 15 cm
e. 11cm
Homework Answers
Change in height = L*coefficient of linear expansion *Delta T
= 320*13*10^-6*(35 +20) = 0.2288 m = 23 cm
