A cylindrical bronze sleeve (2) is held in compression against a rigid machine wall by a high-strength steelbolt (1), as shown in the figure. The steel [E = 200 GPa; a = 11.7 x 106/°C] bolt has a diameter of 29 mm.The bronze [E = 100 GPa; a = 22.0 x 106/°C] sleeve has an outside diameter of 74 mm, a wall thicknessof 8 mm, and a length of L = 390 mm. The end of the sleeve is capped by a rigid washer with a thicknessof t = 5 mm. At an initial temperature of T₁ = 14°C, the nut is hand-tightened on the bolt until the bolt,washers, and sleeve are just snug, meaning that all slack has been removed from the assembly, but no stresshas yet been induced. If the assembly is heated to T2 = 59°C, calculate the normal stress (positive if tensileand negative if compressive) in the bronze sleeve. Answer in MPa rounded-off to 2 decimal places.
