An aluminum alloy [e = 73 gpa] cylinder (2) is held snugly between a rigid plate and a foundation by two steel bolts (1) [e = 180 gpa]. the aluminum cylinder has a length of l2 = 275 mm and a cross-sectional area of 2300 mm2. each steel bolt has a length of l1 = 335 mm and a diameter of d1 = 14 mm. the bolt has a pitch of 1 mm. this means that each time the nut is turned one complete revolution, the nut advances 1 mm. the nut is hand-tightened on the bolt until all slack has been removed from the assembly but no stress has yet been induced. determine the magnitude of the normal stress produced in the aluminum cylinder when the nut is tightened one complete turn past the snug-tight condition.
