Stress, Strain and Young Modulus
 

Stress, Strain and Young Modulus problem 25


A length of steel wire and a length of brass wire are joined together. The combined wires are suspended from a fixed support and a force of is applied, as shown.




The Young modulus of steel is . The Young modulus of brass is . Each wire has a cross-sectional area of . The wires obey Hooke’s law. What is the total extension? Ignore the weights of the wires.
