A circular disc is to be made using iron and aluminum. To keep its moment of inertia maximum about a geometrical axis, it should be so prepared that:
- Aluminum at interior and iron surrounds it
- Iron at interior and aluminum surrounds it
- Aluminum and iron layers in alternate order
- Sheet of iron is used at both external surfaces and aluminum sheet as inner material
Answer
(B) Iron at interior and aluminum surrounds it
