Q: Linear strains along X, Y and Z directions in an object with homogenous material are given as 0.05, 0.10 and 0.10, respectively. The size of the object before deformation was 20 cm × 10 cm × 10 cm. Determine the volumetric strain and change in volume of the material after deformation.
  • A. Volumetric strain = 0.25, change in volume = 5 × 10⁵ mm³
  • B. Volumetric strain = 0.7, change in volume = 1400 cm³
  • C. Volumetric strain = 0.3, change in volume = 60 × 10⁴ mm³
  • D. Volumetric strain = 0.25, change in volume = 500 mm³
