Manufacturing Industries Class 10 MCQs With Answers

The correct answer is "all above points". This means that manufacturing is important for all the mentioned reasons: technologically, economically, and historically. Technologically, manufacturing plays a crucial role in developing and advancing technologies. Economically, it contributes to the growth and stability of a country's economy. Historically, manufacturing has been a significant part of human civilization, driving progress and societal development. Therefore, all these points highlight the importance of manufacturing.

Manufacturing capability refers to the overall ability of a company to produce goods. This includes both the technological processing capability, which refers to the company's ability to use advanced technology and processes in manufacturing, as well as the physical product limitations, which refers to any constraints or limitations in the design or production of the product. Additionally, manufacturing capability also includes the production capacity, which refers to the maximum amount of goods that a company can produce within a given time period. Therefore, the correct answer is A+B, as it encompasses all these aspects of manufacturing capability.

Secondary industries refer to the sector of the economy that takes the outputs of primary industries, such as raw materials or agricultural products, and converts them into consumer and capital goods through the process of manufacturing. This means that secondary industries play a crucial role in transforming raw materials into finished products that are ready for consumption or further use. Therefore, the statement that "manufacturing is the principal activity" in secondary industries aligns with the explanation provided.

The correct answer is "all above points." The explanation for this answer is that manufacturing refers to the production of goods or products, typically done on a large scale. It involves the process of making or creating items, which can include everything from nuts and bolts to cars and computers. The term "manufacturing" is derived from the Latin words manus, meaning hand, and factus, meaning make, suggesting that it originally referred to items made by hand. However, in modern times, manufacturing is often done using machinery and automation. Therefore, all the points mentioned in the question are valid explanations of what manufacturing is.

The company must organize itself by adding all of the mentioned departments in the factory. Manufacturing engineering department is responsible for designing and improving manufacturing processes. Production planning and control department ensures efficient production by managing resources and scheduling. Quality control department ensures that products meet the required standards. Therefore, all three departments are necessary for the smooth functioning and success of the company.

Steel and cast iron are both alloys of iron and carbon. The given answer states that steel typically contains a carbon content ranging from 0.02% to 2.11%, while cast iron typically contains a higher carbon content ranging from 2% to 4%. This is an accurate explanation of the carbon content in these two types of alloys.

The correct answer is A+B because traditional ceramics and modern ceramics both involve the use of clay (hydrous aluminum silicates) and alumina (Al2O3).

The correct answer is A+B because production systems can be categorized into two main categories: production facilities and manufacturing support systems. Production facilities refer to the physical locations where the production process takes place, including factories, plants, or workshops. On the other hand, manufacturing support systems include the people, equipment, and procedures that support the production process, such as quality control, maintenance, and logistics. Therefore, the combination of A (production facilities) and B (manufacturing support systems) covers the different categories of production systems.

The given products have in common the fact that they are all manufactured. This means that they are not naturally occurring but rather created through a production process. The statement does not provide any specific details about the products or their purpose, but it highlights the commonality of being manufactured.

Thermosetting polymers are the correct answer because they chemically transform or cure into a rigid structure and cannot be reheated. Unlike thermoplastic polymers, which can be melted and reshaped multiple times, thermosetting polymers undergo a permanent chemical change when heated, resulting in a rigid and infusible structure. Elastomers, on the other hand, are a type of polymer that can be stretched and returned to their original shape, so they do not fit the given description. Therefore, the correct answer is thermosetting polymers.

Manufacturing adds value to the material by changing its shape or properties, or by combining it with other materials. This means that through the manufacturing process, the material undergoes transformations that enhance its usefulness or functionality. These changes can include shaping the material into a desired form or altering its physical or chemical properties to meet specific requirements. Additionally, manufacturing may involve combining the material with other substances to create new composite materials with enhanced characteristics. Therefore, the correct answer is "both a and b."

The correct answer is 1. Metals, 2. Ceramics, and 3. Polymers. This is because most engineering materials can be categorized into one of these three basic categories. Metals are known for their high strength and conductivity, ceramics are known for their high heat resistance and hardness, and polymers are known for their flexibility and low density. These three categories cover a wide range of materials used in engineering applications.
