Ultimate Quiz On Engineering Materials And Components

Grass is not considered an engineering material because it does not possess the necessary properties and characteristics required for engineering applications. Unlike polymers, glass, and metal, grass does not have the strength, durability, and versatility needed for use in construction, manufacturing, or other engineering fields. Grass is primarily used as a natural ground cover or for agricultural purposes, rather than being utilized in engineering projects.

The statement "Thermal property is associated with heat" is true because thermal property refers to the characteristics and behavior of a substance or material when it is exposed to heat. Heat is the energy transfer that occurs due to temperature differences, and thermal properties describe how a substance responds to this energy transfer, such as its conductivity, expansion, and specific heat capacity. Therefore, heat is closely related to thermal properties, making the statement true.

Heat can be used to alter a product in various ways. It can be used to change the physical properties of materials, such as melting or solidifying them. Heat can also be used to induce chemical reactions, such as in cooking or baking. Additionally, heat can be used for sterilization or to remove moisture from a product. Therefore, it is true that using heat is one of the major ways of altering a product.

Yes, a material can be altered. This means that it can be changed or modified in some way, either through physical or chemical processes. Altering a material can involve various actions such as cutting, shaping, heating, cooling, mixing, or combining it with other substances. These alterations can result in changes to the material's properties, composition, or appearance.

Magnets have the ability to attract and repel other magnetic materials. This attraction and repulsion is known as a magnetic reaction. Therefore, it can be said that magnets hasten or speed up the magnetic reaction between themselves and other magnetic materials. Hence, the statement "Magnets hasten magnetic reaction" is true.

The question asks for a material that is not a beverage material. Aluminum, polymers, and metal can all be used as beverage materials, as they are commonly used in the production of cans, bottles, and other containers. However, ore is not a beverage material. Ore refers to a natural material that contains a valuable mineral or metal that can be extracted and processed, but it is not used directly as a beverage material.

The correct answer is "Electric property." In the context of an electric field, a stimulus refers to something that causes a change or response in the field. An electric property, such as charge or voltage, can act as a stimulus to an electric field, influencing its strength or direction. Electric waves and electric cushion are not directly related to the concept of a stimulus in an electric field.

Materials engineers create materials using old materials, which means they take existing materials and use them to develop new materials or improve existing ones. They may use old materials as a base to create new products or recycle them to create new materials. This process allows for the efficient use of resources and reduces waste by repurposing old materials instead of starting from scratch.

Material scientists are individuals who specialize in the study and development of materials. They are involved in researching and improving existing materials, as well as creating new materials. Their expertise lies in understanding the properties and behaviors of various substances, and using this knowledge to invent and design innovative products or solutions. The statement "They make new things" accurately captures the essence of their role in creating novel materials and applications.
