Q-1 A solid circular rod with a diameter d= 18 mm is shown in Figure Q-3. The rod is made of an aluminum alloy that has an elastic modulus E = 72 GPa and a Poisson's ratio v = 0.32. When subjected to the axial load P, the diameter of the rod decreases by 0.025 mm. For a factor of safety of 1.75, a) Determine the magnitude of the safe allowable load P. b) If we have a 12 mm diameter hole theough the rod, making it a hollow member (a pipe), other things remaining the same as in part (a), determine the magnitude of load P P
