Question 1: Describe the process of using a drill to create a hole in a piece of wood. Include safety considerations and tools needed.

Answer: The process involves selecting the correct drill bit for the material, securing the wood to prevent movement, wearing safety goggles, and applying steady pressure while drilling. Ensure the drill is set to the appropriate speed and that the workspace is clear of obstructions.

Question 2: Explain how a soldering iron is used to join two metal components. Mention safety precautions and common applications.

Answer: A soldering iron heats up and melts solder to join metal components, such as wires or electronic parts. Safety precautions include wearing safety goggles, working in a well-ventilated area, and handling the hot iron carefully. It is commonly used in electronics assembly and repair.

Question 3: Sketch a simple design of a hand-held tool that could be used to tighten small screws. Label the main parts of your design.

Answer: A correct sketch would show a tool with a handle, a shaft, and a turning head (like a mini screwdriver). Labels should include the handle, shaft, and head. The design should be ergonomic and suitable for small screws.

Question 4: Describe the process of using a glue gun for bonding materials. Include tips for achieving a strong bond and safety advice.

Answer: The glue gun is plugged in and heated until the glue melts. The glue is then applied to the surfaces to be bonded. Press the materials together firmly until the glue cools and hardens. Safety tips include avoiding contact with hot glue and unplugging the gun when not in use.

Question 5: Design a simple plan for creating a cardboard model of a new product. Include the key steps and tools required.

Answer: Steps include sketching the design, cutting cardboard with a craft knife, scoring fold lines, assembling parts with glue or tape, and reinforcing joints. Tools needed are scissors, a craft knife, ruler, glue, and tape.

Question 6: Explain what a lathe machine is used for and describe how it shapes materials.

Answer: A lathe machine is used to shape materials like wood or metal by rotating the workpiece against cutting tools. It can produce cylindrical shapes, threads, and detailed patterns by controlling the cutting tool's movement and speed.

Question 7: Sketch a design for an ergonomic handle suitable for a hand tool. Include key features that improve comfort and grip.

Answer: A good sketch would show a handle with a contoured shape that fits the hand, possibly with textured grip areas, and a smooth surface for comfort. The handle should be positioned for natural wrist alignment.

Question 8: Describe how welding can join metal parts together. Mention types of welding and safety measures.

Answer: Welding involves applying heat and sometimes pressure to fuse metal parts. Types include arc welding and MIG welding. Safety measures include wearing protective clothing, welding mask, gloves, and working in a well-ventilated area to avoid fumes.

Question 9: Identify and explain two techniques used to finish and smooth a plastic surface after shaping.

Answer: Sanding with fine-grit sandpaper removes rough edges and creates a smooth surface. Polishing with a soft cloth and polishing compound can then give the plastic a shiny finish.

Question 10: Create a step-by-step plan for assembling a simple wooden box. Include the techniques you would use at each stage.

Answer: Steps include measuring and marking the wood, cutting pieces with a saw, sanding edges, drilling holes for screws, assembling parts using screws or nails, applying wood glue for additional strength, and finishing with sanding and varnishing.
