the gage marks was 3.0 mm and the minimum diameter was
10.7 mm.

1.5-2 A bar of length 2.0 m is made of a structural steel
having the stress-strain diagram shown in the figure. The
yield stress of the steel is 250 MPa and the slope of the ini-
tial linear part of the stress-strain curve (modulus of elas-
ticity) is 200 GPa. The bar is loaded axially until it
elongates 6.5 mm, and then the load is removed.
How does the final length of the bar compare with
its original length? (Hint: Use the concepts illustrated in
Fig. 1-36b.)
