Given a Barrel of diameter 134.122 cm at 20 c it is your job to attach an iron band around this barrel. The circular band be heated so that it will fit over the barrel. The circular band has an inside diameter of 134.110 cm at 20 c .
a) To what temperature must be the band be heated so that it will fit over the barrel?
B) What will be the tension in the band when it cools to 20 c ? The band is 9.4 cm wide and 0.65 cm thick.
C) Will this tension exceed the yield strength of iron? Compare the thermal stress in this band to the yield strength for iron.
