Stress, Strain and Young Modulus
 

Stress, Strain and Young Modulus problem 37


A steel wire and a brass wire are joined end to end and are hung vertically with the steel wire attached to a point on the ceiling. The steel wire is twice as long as the brass wire and has half the diameter. A large mass is hung from the end of the brass wire so that both wires are stretched elastically. The Young modulus for steel is and for brass is . What is the ratio of the extension of the steel to the extension of the brass?
