Question

A steel rod has length 60.3 cm and radius 2.20 cm. An aluminum rod has length 20.0 cm and radius 2.20 cm. The rods are joined end to-end. When compressive forces of magnitude 5.40 are applied to the ends, by how much does the total length of the rods decrease? Young's modulus of steel is 200 * 10 ^ 11 * N / (m ^ 2) and Young's modulus of aluminum is 700 * 10 ^ 10 * N / (m ^ 2) m

A steel rod has length 60.3 cm and radius 2.20 cm. An aluminum rod has length 20.0 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 x 1011 N/m2 and Young's modulus of aluminum is 7.00 × 1010 N/m2.
