Question 1: Describe the process of using a vice and saw to cut a piece of wood accurately. Include safety precautions you should take.

Answer: Use the vice to securely hold the wood on a stable surface. Mark the cut line clearly with a pencil. Use a saw to cut along the line smoothly, applying even pressure. Wear safety goggles and keep fingers away from the blade. Ensure the work area is clear of obstructions.

Question 2: Explain how a soldering iron is used to join electrical components. Include safety measures.

Answer: A soldering iron heats up and is used to melt solder onto electrical connections, creating a secure bond. The tip is touched to the component lead and pad, then solder is applied. Safety measures include wearing safety goggles, working in a well-ventilated area, and handling the hot iron with care to prevent burns.

Question 3: Sketch a simple plan for assembling a small wooden box with a lid, indicating the types of joints you would use.

Answer: A clear plan showing the box sides joined with butt joints reinforced with nails or glue, and the lid fitting into the top with either a lap joint or a hinge. The sketch should include labels for each part and joint type.

Question 4: Create a labelled sketch of a handle designed for ergonomic comfort. Show how the shape fits the hand and suggest suitable materials.

Answer: A sketch of a handle with a curved, contoured shape that fits the natural grip of the hand. The labels should point to the ergonomic curves, textured surface for grip, and indicate materials like rubber or soft plastics.

Question 5: Describe the process of using a lathe to create a symmetrical cylindrical wooden or metal component. Include key safety tips.

Answer: Mount the piece securely in the lathe chuck. Set the desired dimensions and turn on the lathe. Use cutting tools to shape the material, applying steady pressure while the workpiece spins. Safety tips include wearing eye protection, keeping hands away from the spinning part, and ensuring the workpiece is firmly secured.

Question 6: Explain the purpose of using a file in finishing a metal or wooden component. How does it improve the product?

Answer: A file smooths rough edges and surfaces, removing burrs and uneven areas. It improves the product’s appearance and safety by preventing cuts or snags, and ensures parts fit together accurately.

Question 7: Draw a plan for creating a prototype of a new product using cardboard. Indicate how you would cut, fold, and assemble the pieces.

Answer: The plan should include sketches of the cardboard pieces with marked cut lines, fold lines, and tabs for joining. Indicate where glue or tape will be used for assembly, showing a step-by-step folding sequence.

Question 8: Describe how injection moulding is used to produce plastic parts efficiently. Include key steps in the process.

Answer: Plastic granules are heated until molten and injected into a pre-made metal mould under high pressure. Once cooled, the mould is opened, and the solid plastic part is ejected. The process allows for high-volume production with consistent quality.

Question 9: Sketch a cross-sectional view of a simple riveted joint used to connect two metal plates. Show the placement of the rivet and how it secures the plates.

Answer: A cross-section showing two metal plates overlapping with a rivet passing through aligned holes. The rivet head is on one side, with the tail on the other, secured by peening or deformation to hold the plates together.

Question 10: Describe the process of using a hot glue gun to assemble a small product. Mention safety tips and best practices.

Answer: Insert a glue stick into the gun and allow it to heat up. Squeeze the trigger to extrude hot glue onto the joining surfaces. Press parts together firmly until the glue sets. Safety tips include wearing gloves if necessary, avoiding skin contact with hot glue, and working in a well-ventilated area.
