A plastic rod AB of length L = 520 mm has a diameter d, = 30 mm as shown in Figure Q2(b). A plastic sleeve CD of length c = 300 mm and outer diameter d2 = 45 mm is securely bonded to the rod so that no slippage can occur between the rod and the sleeve. The rod is made of an acrylic with modulus of elasticity E1 = 3.1GPA and the sleeve is made of a polyamide with E2 = 2.5GP . (i) Calculate the elongation & of the rod when it is pulled by axial forces P=15KN. (ii) If the sleeve is extended for the full length of the rod, what is the elongation? (iii) If the sleeve is removed, what is the elongation?

The particle has a mass of 0.45 kg and is confined to move along the smooth horizontal slot due to the rotation of the arm OA. Assume the particle contacts only one side of the slot at any instant. The arm has an angular acceleration of 0 = 3 rad/s² when 0 = 2 rad/s at 0 = 30° (Figure 1) Figure 6 = 2 rad/s 99°F Sunny r A 0.5 m 1 of 1 < Re
