A) The bulk modulus of polycarbonate is 14.2 GPa. Calculate the hydrostatic pressure (stress) needed for a sample of this material to change volume by 3.0 %. 8) The Young's modulus of polycarbonate is 2.4 GPa. A polycarbonate rod of diameter 3.0 mm is subject to a force of 750 N along its length. Calculate the stress and the percentage increase in the length of the rod when the stress is applied.
