A steel rod has length 59.0 cm and radius 2.20 cm. An aluminum rod has length 20.7 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 andYoung's modulus ofaluminum is 7.00 10¹⁰ N/m².
