Problem #3
The two solid circular rods with a= 6.6x10*/"F
are in an initial stress-free state at a temperature
of 85 °F, and then the rods are heated to a
temperature of (158+ a) "F.
E= 16,000 ksi
E-27,000 ksi
6 in.
a) Using the given temperature increase,
determine the normal stress in each bar AB
B 3 in.
and BC.
b) Using the same temperature increase, if there is
an initial gap at Cof dc (0.008 + 0.003 b) in.,
determine the normal stress in each bar AB
4+0.3c ft-
2+0.le ft -
and BC.
(Note: Provide your answers in units of ksi using
4 significant digits of accuracy. For each bar indicate
if the stress is Tension or Compression.)
