l = change in length

Length = 10 cm

Cross-Sectional Area = 1 cm2

Young's Modulus = 200 GPa

Applied Load = 1000 kN

Find answer in cm.

The answer is 0.5 cm; however, I cannot figure out how to find this answer. Any help is appreciated.

= .1m*1000kN/200GN/m^2*1/1E-4m^2=

=.1*1E6/200E9 *1/E-4=.1/2 * 1E(6-11+4)

= .05E-1 m=.5cm
