A cylindrical specimen of a brass alloy 8.3 mm (0.33 in.) in
diameter and 76.7 mm (3.02 in.) long is pulled in tension with a
force of 7360 N (1655 lbf); the force is subsequently
released.
(a) Compute the final length of the specimen at
this time. The tensile stress-strain behavior for this alloy is
shown in Animated Figure 7.12.
(b) Compute the final specimen length when the
load is increased to 20300 N (4563 lbf) and then released.

A 580-mm long tungsten wire, with a 0.046-mm-diameter circular
cross section, is wrapped around in the shape of a coil and used as
a filament in an incandescent light bulb. When the light bulb is
connected to a battery, a current of 0.526 A is measured through
the filament. (Note: tungsten has a resistivity of 4.9 × 10-8 ? •
