Challenge Problems

Push your limits with challenges.

Question 1

A rectangular beam made of isotropic material experiences uniform tension. If the original length is 10m and it elongates by 1mm under a stress of 50MPa, calculate the Young's modulus of the material.

💡 Hint: Apply the relationship of stress and strain directly to find E.

Question 2

If a cube of isotropic material with known Young's modulus is compressed and experiences a change in volume, how can you derive the bulk modulus using the relationship of stress and strain?

💡 Hint: Think about the different components contributing to the change in volume in relation to pressure.
