Challenge Problems
Push your limits with advanced challenges
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.
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.
