r = 10^-3 meters
stress = F/area = 40/ (pi r^2) = 40 /( pi * 10^-6)
strain = elongation/length = 0.24*10^-3 / 4
Young mod = stress/strain =
stress = F/area = 40/ (pi r^2) = 40 /( pi * 10^-6)
strain = elongation/length = 0.24*10^-3 / 4
Young mod = stress/strain =

Stress=Force\Area
=40\3.142(1×10^-3)^2
Stress=1.27×10^-7
=40\3.142(1×10^-3)^2
Stress=1.27×10^-7
