Homework Help: Science/Biomaterials

Posted by James on Sunday, June 3, 2012 at 7:24pm.

Given the following properties, how much stretch would you expect to occur in a specimen of polyethylene to which a tensile load is applied?

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.
