Question

A copper wire of length 2.4 m and a steel wire of length 1.6 m, both of diameter 3 mm, are connected end to end. When stretched by a load, the net elongation found to be 0.7 mm. The load applied is (Y_("Copper") = 1.2 × 10^(11) N m^(-2), Y_("steel") = 2 × 10^(11) N m^(-2)).

Name: a copper wire of length 24 m and a steel wire of length 16 m both of diameter 3 mm are connected end to end when stretched by a load the net elongation found to be 07 mm the load appled is y 22209

Step 1

4 \, \text{m} \) - Length of steel wire, \( L_{\text{Steel}} = 1.6 \, \text{m} \) - Diameter of both wires, \( d = 3 \, \text{mm} = 3 \times 10^{-3} \, \text{m} \) - Net elongation, \( \Delta L_{\text{total}} = 0.7 \, \text{mm} = 0.7 \times 10^{-3} \, \text{m} \) - Show more…
