A plastic sleeve CD of length c = 300 mm and outer diameter d, = (45+ A) 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 E, = 3.1GPA and the sleeve is made of a polyamide with E, = 2.5GP . The value of A, B and C are given by: A=the last digit of your matrix number B=the fifth digit of your matrix number C= the forth digit of your matrix number For example, a student with the matrix number CD200187 will have the values of L=510mm, d, = 38 mm and d, =52 mm. (i) Calculate the elongation 8 of the rod when it is pulled by axial forces P=12kN. (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?
