An assembly of a bronze tube and a steel bolt is shown in the figure. The pitch of the bolt thread is 0.8 mm. The cross-sectional area of the bronze tube is 900 mm² and of the steel bolt is 450 mm². The nut is turned until there is a compressive stress of 30 Mpa in the bronze tube. Find the stress in the bronze tube if the nut is given one additional turn. How many turns of the nut will reduce this stress to zero?
