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:
a. | the same stress |
b. | different stress |
c. | the same strain |
d. | different strain |
Choose the correct option:
1. | (a, b) |
2. | (a, d) |
3. | (b, c) |
4. | (c, d) |
