Question

What force would be required to stretch a wire of 3×10-4 m2 cross section, so that its length
becomes 2.5 times its original length? Given that Young’s modulus of the material of the wire is
3.6×1011 Nm-2

Answer 1

Answer:

A=2x10-4m 2 , Y=3.6x1011Nm-2 Let L original length then ∆L=1.5L- L=0.5L
