Question

A plastic rod AB of length L = 0.5 m has a diameter d₁ = 30 mm (see figure). A plastic sleeve CD of length c = 0.3 m 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 a modulus of elasticity E₁ = 3.1GPa, and the sleeve is made of a polyamide with E₂ = 2.5 GPa.
(a) Calculate the elongation d of the rod when it is pulled by axial forces P =12 kN.
(b) If the sleeve is extended for the full length of the rod, what is the elongation?
(c) If the sleeve is removed, what is the elongation?
