    Correct Answer
    A. True
    Explanation
    The bonding of atoms in a material directly influences its mechanical properties. The type of bonds formed between atoms determine the strength and stability of the material, which in turn affects its ability to withstand external forces and deformation. For example, materials with strong metallic bonding, such as steel, tend to have high tensile strength and are resistant to breaking, while materials with weak bonding, such as ceramics, may be brittle and easily fractured. Therefore, it is true that the bonding of atoms in a material has an effect on its mechanical properties.

    Cast iron materials are brittle.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Cast iron materials are brittle because they have a high carbon content, which makes them prone to fracture under stress. Unlike other types of iron, cast iron does not have a ductile or malleable property, meaning it cannot be easily stretched or bent without breaking. This brittleness is due to the formation of graphite flakes within the material, which act as stress concentrators and weaken its structure. As a result, cast iron is not suitable for applications that require flexibility or impact resistance.

    Correct Answer
    A. True
    Explanation
    Ductility refers to the ability of a material to be stretched or deformed without breaking. Ferrous materials, which include iron and steel, are known for their high ductility, which makes them suitable for construction materials. This property allows them to withstand the forces and stresses that may be applied during construction, such as bending or stretching, without fracturing. Therefore, it is true that ductility is a key characteristic of ferrous materials selected for construction materials.
