What characteristics do you think the zine provides to this coated, or galvanized, steel? What precautions should be considered in producing this product? How will the recyclability of the product be affected? TQ2: We would like to produce a transparent canopy for an aircraft. If we were to use a ceramic (that is, traditional window glass) canopy, rocks or birds might cause it to shatter.

Would you select this material for a spring? Explain. TQ4: 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?
