curvatul where at the angular Tv nergy Page 11 of 12 QA3 A brass sleeve S is fitted over a steel bolt B (See Fig QA3) and mitted over a steel bolt B (See Fig OA) and the nut is tightened until it is just snug. The bolt has a diameter de = 25 mm and the sleeve has inside and outside diameters dı - 28 mm and dy - 37 mm, respectively. (a) Calculate the temperature rise At that is required to produce a compressive of 26 MN/m2 in the sleeve. [14 marks] (b) Find the change in the length of the sleeve if the overall length of the sleeve is 150 mm [6 marks Use material properties as follows: For the sleeve, as = 21 x 106/C and Es = 100 GN/m2 For the bolt, de = 10 x 10°C and Es = 200 GN/m2 da di do Sleeve (3) Bolt (B) Fig. QA3 Total marks Page 4 of 12
