The Young modulus for the wire is  7.44 * 10^9  N/m^2.

What is the stress of the wire?

For the wire that is under discussion here, we have the following parameter for the wire;

Length of the wire = 20-m

Diameter of the wire = 3.2mm

Extension of the wire = 50 cm

strain of the wire = extension/ length of the wire

strain of the wire = 50 * 10^-2 m/20 m

= 0.025

The stress of the wire = Force/Area

= 1500 N/(3.14 * (3.2 * 10^-3)^2/4)

= 1.86 * 10^8 N/m^2

Young modulus = Stress/strain = 1.86 * 10^8 N/m^2/ 0.025

= 7.44 * 10^9  N/m^2
