Answer:
Contraction of Chicago concrete walkway = 8.64 x 10⁻³ m
Explanation:
Thermal expansion or compression is given by ΔL = LαΔT
Here Length of Chicago concrete walkway, L = 18 m
Change in temperature, ΔT = (-16 - 24) = -40 °C
Coefficient of thermal expansion for concrete, α = 12 x 10⁻⁶ °C⁻¹
Substituting
ΔL = LαΔT = 18 x 12 x 10⁻⁶ x (-40) = -8.64 x 10⁻³ m
Contraction of Chicago concrete walkway = 8.64 x 10⁻³ m
