When builders were constructing a sidewalk they forgot to include an expansion joint between two of the segments, L = 1.4 m at To = 17° Celsius. Assume the opposite ends of each segment are fixed and the linear expansion coefficient is ? = 11.4*10-6 C-1.
Part (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 at Tb in m? Given Tb = 110 degrees Fahrenheit.
Numeric : A numeric value is expected and not an expression. h = __________________________________________
Part (b) What should the gap have been to prevent them from touching in m? Numeric : A numeric value is expected and not an expression.
g = __________________________________________
