Each section of the sky way is 1.7 km long, and each segment has a cross-sectional area of 117.4 m2. Due to the hot weather the skyway has expanded by 2.5 %. How much force is exerted by each segment on another at the expansion joint? (The Young's modulus of concrete is 46.1 GPa.) Please give the answer in Giga Newtons.
