A steel rod has length 57.9 cm and radius 2.20 cm. An aluminum rod has length 35.3 cm and radius 2.20 cm. The rods are joined end-to-end. When compressive forces of magnitude 5.40 kN are applied to the ends, by how much does the total length of the rods decrease? Young’s modulus of steel is 2.00 × 1011 N/m2 and Young’s modulus of aluminum is 7.00 × 1010 N/m2.
