A steel rod with a diameter of 24 mm is provided with a screw thread on each end and also nuts having a pitch of 1,0 mm. A pipe of the same material which is 1,2 m long with an internal diameter of 26 mm and a thickness of 8 mm, is positioned between the two nuts and necessary washers of negligible thickness. The nuts are tightened to produce an initial stress of 15 kPa in the pipe. Calculate the initial stress in the rod, as well as the increase in stress in the rod and the pipe when the nut is tightened ONE revolution. Take E for steel as 210 GPa.
