Figure 1: Spark blog body
A. Based on the electrical material properties. What you will choose to manufacture part 1 (It's a wire
to conduct current) (Nickel, Lead, or Aluminium). Give reasons for your choice.
B. To insulate the outer cover of the spark blog; part 2 is added, what material will you use (Borcelain,
Fiberglass or Lead). Give reasons for your choice.
C. Choose the best material to design the side electrode (Part 3) to have the highest heat conductivity
(Iron, Tin, Stainless Steel). Explain the reason behind your selection.
D. What material will you choose to design the outer terminal (Part 4) to have a highest strength level
(Steel, Brass, Copper). Explain your answer.
E. Define mechanical property of an engineering material. State three mechanical properties and give
one example of the material possessing each property.
F. List two physical properties.
