The oldest archaeological evidence of copper mining and working was the discovery of a copper
Correct Answer
B. Pendant
Explanation
The correct answer is Pendant. The explanation for this is that the oldest archaeological evidence of copper mining and working was the discovery of a copper pendant. This suggests that early civilizations were using copper to create decorative jewelry items such as pendants.
2.
The hand tool designed to precisely measure the distance between two points is known as
Correct Answer
A. Calipers
Explanation
Calipers are a hand tool designed for precise measurement of distances between two points. They consist of two hinged legs with inward-facing tips that can be adjusted to fit around an object or gap. By comparing the distance between the tips with a scale or ruler, accurate measurements can be obtained. Calipers are commonly used in fields such as engineering, machining, and woodworking where precise measurements are essential.
3.
.................is the process of working with metals to create individual parts, assemblies, or large-scale structures
Correct Answer
C. Metalwork
Explanation
Metalwork is the correct answer because it involves the process of working with metals to create individual parts, assemblies, or large-scale structures. This can include activities such as shaping, cutting, bending, and joining metals to produce various objects or components. Metalwork is a broad term that encompasses various techniques and skills used in the fabrication and manipulation of metal materials.
4.
Select the odd one out
Correct Answer
D. Pasting
Explanation
The odd one out is "Pasting" because it is the only action that involves attaching or sticking something together, while the other options (Forming, Cutting, Joining) involve creating or combining different elements.
5.
The process of transferring a design or pattern to a workpiece and is the first step in the handcraft of metalworking is called
Correct Answer
D. Marking out
Explanation
Marking out is the correct answer because it refers to the process of transferring a design or pattern onto a workpiece in order to guide the subsequent metalworking activities. This step is crucial as it ensures accuracy and precision in the final product. By marking out, the craftsman creates reference points, lines, and measurements on the workpiece, which serve as a guide for shaping, cutting, drilling, or any other metalworking technique that will be performed. Therefore, marking out is an essential initial step in the handcraft of metalworking.
6.
Which of the followng belongs to the category of metalworking
Correct Answer
C. Joining
Explanation
Joining belongs to the category of metalworking because it involves the process of connecting or combining metal parts together. This can be done through techniques such as welding, soldering, or brazing. Joining is a fundamental aspect of metalworking as it allows for the creation of complex structures and the assembly of various metal components. On the other hand, duplicate copying, painting, and sketching do not involve the manipulation or fabrication of metal materials, and therefore do not fall under the category of metalworking.
7.
Pouring molten metal into a mold and allowing it to cool to form a desired shape is called
Correct Answer
A. Casting
Explanation
Casting is the correct answer because it involves the process of pouring molten metal into a mold and allowing it to cool and solidify, resulting in the desired shape. This method is commonly used in manufacturing industries to create various objects and components with complex shapes and structures. Sketching and designing are unrelated to this process, while scrapping refers to the act of discarding or destroying something.
8.
Which of the following is part of the forming process
Correct Answer
B. Sheet forming process
Explanation
Sheet forming process is part of the forming process. This process involves shaping a sheet of material, such as metal or plastic, into a desired form using various techniques like bending, stretching, or deep drawing. It is commonly used in industries like automotive, aerospace, and manufacturing to create components and products with specific shapes and dimensions. The other options, sketching process, cooling process, and drying process, are not directly related to the forming process.
9.
Which of the following is not part of the cutting process
Correct Answer
C. Clearing
Explanation
Clearing is not part of the cutting process because it refers to the removal of debris or vegetation from a specific area, rather than the actual act of cutting or shaping materials. Chipping involves the removal of small pieces or fragments from a larger material, burning involves the use of heat to cut or melt materials, and miscellaneous specialty processes refer to specific techniques or methods used in cutting.
10.
A set of processes wherein the metal is cut by oxidizing a kerf to separate pieces of metal is called
Correct Answer
A. Burning
Explanation
Burning is the correct answer because it refers to a process where the metal is cut by oxidizing a kerf to separate pieces of metal. This process involves the use of heat to rapidly oxidize the metal, causing it to burn and separate into smaller pieces. It is commonly used in industries such as metal fabrication and demolition to cut through thick metal sheets or structures.
