A composite wire of steel and copper of diameters 1 cm and length 2 2 m and 2m respectivly - Physics - Mechanical Properties Of Solids

Question

A composite wire of steel and copper of diameters 1 cm and
length 2 2 m and 2m respectivly total extension of the wire when
streched by a force is 1 2mm calculate the force given that youngs
modulus for copper is 1 1x1011and steel
2x1011Pa

Hi Salha!
Given,
Length of steel wire = 2
2m
Length of copper wire =
2m
Young’s modulus of copper
(YC) = 1 1×1011Pa
Young’s modulus of steel
(YS) =2×1011Pa
Diameter = 1cm
Area of cross section =
πr2= π× 0 005=0
0157m2
