Question

A composite wire is prepared by joining
a tungsten wire and steel wire end to end.
Both the wires are of the same length
and the same area of cross section. If this
composite wire is suspended to a rigid
support and a force is applied to its free
end, it gets extended by 3.25mm. Calculate
the increase in length of tungsten wire and
steel wire separately,
[Given: Y = 2 x 10' N/m,
Y
= 3.40 x 108N/m]
[Ans: extension in tungsten wire = 3.244 mm,
extension in steel wire = 0.0052 mm]
steel
Tungsten​

Answer 1

Answer:

3.244mm

Explanation:

Given: Y = 2 x 10' N/m,

Y

= 3.40 x 108N/m]

[Ans: extension in tungsten wire = 3.244 mm,

extension in steel wire = 0.0052 mm]

steel

Tungsten
