A plastic rod AB of length L= 5C 0 mm has a diameter d, = 3B mm as shown in Figure Q2(b). 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 .

![(b) A plastic rod AB of length L= 5C 0 mm has a diameter d, = 3B mm as shown in Figure
Q2(b). 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?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F67568f3b-32de-4148-a4a0-886ef41ada2e%2F2984c54d-641d-4052-8da1-928fe0632c67%2Fr9wclz8_processed.png&w=3840&q=75)
