Question

A copper and a steel wire of the same diameter are connected end to end. A deforming force F is applied to this composite wire, which causes a total elongation of 1 cm. The two wires will have: _________

Answer 1

The copper wire will elongate more than the steel wire under the same force, resulting in a total elongation of 1 cm for the composite wire.

Step-by-step explanation:

The copper and steel wire connected end to end will have different elongations when subjected to the same deforming force F due to their different material properties. Copper is more ductile than steel, meaning it can undergo greater deformation without breaking. Therefore, the copper wire will elongate more than the steel wire under the same force, resulting in a total elongation of 1 cm for the composite wire.

For example, let's assume that the copper wire elongates by x cm and the steel wire elongates by y cm. Since the total elongation is 1 cm, we can write the equation: x + y = 1.

Overall, the copper and steel wires will have different elongations when subjected to the same deforming force, with the copper wire elongating more than the steel wire.
