Challenge Problems
Push your limits with challenges.
Question 1
A metal rod with a thermal expansion coefficient of 12 x 10^-6 /°C is heated from 20°C to 100°C. Calculate the change in length of a 2-meter rod.
💡 Hint: Use the formula for thermal strain and remember to convert temperatures to a single increment.
Question 2
In a composite beam subjected to temperature changes, discuss the impact of differing thermal expansion coefficients on stress distribution.
💡 Hint: Consider how compatible materials react under heat and how that influences overall stability.
