Question
When builders were constructing a sidewalk they forgot to include an expansion joint between two of the segments, L = 2.1 m at To = 20° C. Assume the opposite ends of each segment are fixed and the linear expansion coefficient is α = 11 × 10-6 °C-1.
a.) As the day heats to Tb the segments press against each other and begin to raise the junction a distance h forming a triangle. What is the height (in meters) at Tb=110° F?
b.) What should the gap have been, in units of meters, to prevent them from touching?
