Transcribed Image Text:The concrete sections of a certain superhighway are designed to have a length of 27.0 m. The sections are poured and cured at 10.0°C. What minimum spacing should the engineer leave between the
sections to eliminate buckling if the concrete is to reach a temperature of 43.0°C? (Note: If applicable, Table 1 is available for use in solving this problem.)
You will need to look up the coefficient of thermal expansion for concrete in Table 19.1. cm
Expert Solution
Step 1
Given data:
Initial length (L) = 27 m
Initial temperature = 10o C
Final temperature = 43o C
Take the coefficient of linear expansion of concrete, (α) = 12 x 10^-6 per deg C
Need to determine the minimum spacing required between the sections to eliminate the buckling.
