The Eiffel Tower in Paris is 984 ft tall and is made mostly of steel.
The Eiffel Tower in Paris stands at a height of 984 feet and is primarily constructed of steel.
Problem 14.07
Part A
If this height is measured during winter when the temperature is -8.00 °C, how much additional vertical distance would you need to cover if you decide to climb the tower during a summer heat wave when the temperature rises to 41.3 °C?
Part B
Express the coefficient of linear expansion of steel in terms of degrees Fahrenheit.
2 Answers
Part A) I'll use α = 12e-6/ºC
ΔL = α L ΔT = 12e-6/ºC 984ft (41.3 - -8.00)ºC = 0.582 ft ◄
or almost 7 inches.
Part B) 12e-6/ºC * 5ºC/9ºF = 6.67e-6/ºF ◄
assuming the value of α that I have.
Hope this helps!
