Textbook Question
Chapter 1, Problem 1.16P
Temperature indicators are sometimes produced from a coiled metal strip that uncoils a specific amount when the temperature increases. How does this work: from what kind of material would the indicator be made; and what are the important properties that the material in the indicator must possess?

effect of the cooling rate on the microstructure and hardness of a material
Explain how the properties and structure of different given engineering materials affect their behaviour in given engineering applications
2) Plain carbon steel (mild steel) is widely used in the construction of ships hulls. It is easy to work with, low cost and has good structural integrity when ships are operating in normal water temperatures (3°C to 25°C). Explain what happens to the material if a ship is operated for long periods of time in water temperatures that are at or near to freezing.
2) Aluminium alloy (code 2024 age hardened, also called Duralumin) is widely used in the construction of passenger aircraft. Explain why this is and the reasons for putting a finite life on certain parts of the airframe
Does the creep strength vary with temperature?
