Challenge Problems
Push your limits with advanced challenges
Given a concrete slab with a temperature difference of 30 degrees Celsius and a thermal coefficient of 1 x 10^-6, calculate the warping stress in the interior region if the modulus of elasticity is 3000 kg/cm².
💡 Hint: Keep track of all the variables and units during your calculations.
If the temperature change is expected to vary by 50 degrees Celsius over a year, discuss the potential design implications for a rigid pavement in a region with such temperature swings.
💡 Hint: Think about flexibility and durability in your design choices.
