Question 1: Describe a safe way to cut a piece of wood using hand tools. Include the tools you would use and safety precautions.

Answer: Use a saw such as a handsaw, ensuring the workpiece is securely clamped. Keep fingers away from the blade, wear safety goggles, and saw with controlled, steady strokes.

Question 2: Explain how to join two pieces of plastic together using a heat gun. What are the key steps?

Answer: Heat the plastic evenly with the heat gun until it softens. Align the pieces carefully and press them together until cooled and bonded securely.

Question 3: Sketch a simple plan for a small box with a lid, indicating the main parts and how they fit together. Use labels where appropriate.

Answer: A rectangular box with four sides, a base, and a lid that overlaps slightly to fit snugly. Label the sides, base, and lid. Show how the lid fits over the top of the box.

Question 4: Describe the process of creating a hole in metal using a hand drill. Include safety tips and steps to ensure accuracy.

Answer: Secure the metal piece in a clamp, select the correct drill bit, wear safety goggles, mark the spot, drill slowly with steady pressure, and remove the drill carefully after completing the hole.

Question 5: Draw a cross-section of a simple chair leg showing how it can be strengthened. Indicate any reinforcements or joints.

Answer: A vertical rectangular section with internal reinforcements such as a diagonal brace or multiple joints at the top and bottom for stability.

Question 6: Explain the technique of sanding wood to achieve a smooth surface. What are the different grits of sandpaper you might use?

Answer: Start with coarse grit to remove roughness, then use medium grit to refine, and finish with fine grit for a smooth surface. Sand in the direction of the grain.

Question 7: Sketch a design for a simple hinge mechanism. Show how two parts connect and allow movement.

Answer: Two flat plates connected by a central pin or rod, with one plate attached to a fixed part and the other to the moving part, allowing rotation.

Question 8: Describe how to make a paper prototype of a new product idea. Include materials and steps.

Answer: Use paper sheets, scissors, and glue or tape. Draw the main parts, cut them out, and assemble to test the size and shape of the product concept.

Question 9: Sketch a handle for a toolbox that is ergonomic. Think about comfort and ease of use.

Question 10: Explain the difference between joining techniques: gluing, screwing, and using brackets. When might each be used?

Answer: Gluing is best for smooth, continuous surfaces and provides a clean finish. Screwing is strong and suitable for load-bearing joints. Brackets are used for added support, especially in corners or heavy-duty connections.
