Extracted text: Q2) A brass sleeve S is fitted over a steel bolt B (see figure), and the nut is tightened until it is just snug( no initial stresses). The bolt has a diameter dg = 20 mm, and the sleeve has inside and outside diameters dl = 21 mm and d2 = 31 mm, respectively. if the temperature drops by 100 C Calculate stresses induced in bolt and sleeve. What is the total shortening in the bolt -sleeve assembly . Derive any formula you need (Use material properties as follows: for the sleeve, as = 21 x 106/°C and Es= 100 GPa; for the bolt, ag = 10 x 10/°C and Eg = 200 GPa. d2 di dB Sleeve (S) Bolt (B)
