A composite wire is prepared by joining a tungsten wire and steel wire end to end. Both the wires of same length and the same area of cross section. If this composite why is suspended to a rigid support and a force is applied to its free and, its gets extended by 3.25 millimetre. Calculate the increase in length of tungsten wire and steel wire separately.

(Ans : Extension in tungsten wire= 1.182mm, extension in steel wire= 2.068mm)

Answer 1

Answer:

Since the wires are connected end to end i.e. in series so the force acting on them will be equal. According to given, the length and cross-sectional area of both the tungsten wire and the steel wire are equal.
