Question: Two masses, M 1 and M 2 , are supported by wires of equal length when unstretched. The wire supporting M 1 is an aluminum

Two masses, M₁ and M₂, are supported by wires of equal length when unstretched. The wire supporting M₁ is an aluminum wire 0.7 mm in diameter, and the one supporting M₂ is a steel wire 0.5 mm in diameter. What is the ratio M₁/M₂ if the two wires stretch by the same amount?
