A cube of material measures 1m on each side before deformation. After applying pressure, its dimensions change to 0.95m, 0.95m, and 1.05m. Calculate the volumetric strain.
💡 Hint: Use the volume calculation and relate your findings to the original volume.
Compare the volumetric strain of two materials subjected to the same deformation. One shows a significant change due to its properties, whereas the other shows minimal change. Discuss what factors influence this difference.
💡 Hint: Consider how varying properties of materials can lead to different deformation responses.
