Question

Constants Part A The Eiffel Tower (the figure) is built of wrought iron approximately 300 m tall. Assume the coefficient of thermal expansion of wrought iron is 12 x 10-6 1/C° (Figure 1) Estimate how much its height changes between January (average temperature of 2 °C) and July (average temperature of 25 °C). Ignore the angles of the iron beams and treat the tower as a vertical beam. Express your answer to two significant figures and include the appropriate units. ?1-1 Value Units Submit Request Answer Provide Feedback Next > Figure 1 of 1

Explanation / Answer

increase in temperature=25-2=23oC

coefficient of thermal expansion=12*10-6 /oC

initial height = 300 m

increase in height = 300*12*10-6*23=0.0828 m
