Stress, Strain and Young Modulus
 

Stress, Strain and Young Modulus problem 26


A composite rod is made by attaching a glass-reinforced plastic rod and a nylon rod end to end, as shown.




The rods have the same cross-sectional area and each rod is in length. The Young modulus of the plastic is and the Young modulus of the nylon is . The composite rod will break when its total extension reaches . What is the greatest tensile stress that can be applied to the composite rod before it breaks?
