A concrete sidewalk is constructed between two buildings on a day when the temperature is 86 degrees Fahrenheit. The sidewalk consists of two slabs, each three meters in length and of negligible thickness. As the temperature rises to 113 degrees Fahrenheit, the slabs expand, but no space is provided for thermal expansion. The buildings do not move, so the slabs buckle upward. Determine the vertical distance y in part b of the drawing in fe
