Question 1: Design a simple container that can hold small items. Describe the materials you would choose and explain why.

Answer: A suitable material could be plastic for its lightweight and durability. The design might include a snap-fit lid for easy opening and closing. The explanation should cover reasons like safety, cost, and ease of manufacture.

Question 2: Sketch a plan of a wooden box that could be assembled using joints. Indicate the type of joints you would use and their purpose.

Answer: A correct sketch would show the box with interlocking joints such as dovetail or box joints at the corners. The plan should label the joints and demonstrate how they connect each side securely for strength.

Question 3: Describe the process of using a soldering iron to join two electrical wires. What safety precautions should be taken?

Answer: The process involves heating the soldering iron, applying it to the wire ends, and adding solder to create a secure connection. Safety precautions include wearing eye protection, working in a well-ventilated area, and handling the hot iron carefully to avoid burns.

Question 4: Draw a cross-section of a product that uses a layer of foam for insulation. Label the layers and explain why foam is used.

Answer: The sketch should show an outer shell, an inner lining, and a middle layer of foam. Labels should specify each layer. Foam is used because it provides good thermal insulation and cushioning.

Question 5: Explain how a mould can be used in the manufacturing of plastic parts. Describe the main steps involved.

Answer: A mould shapes the plastic as it cools and hardens. Main steps include designing the mould, injecting molten plastic into it, allowing it to cool, then removing the finished part. The process ensures consistent shapes and sizes.

Question 6: Sketch a design for a handle that is comfortable to grip. Show the ergonomic features and explain your choices.

Answer: The sketch should depict a handle with a curved, contoured shape fitting the hand's natural grip. Features like textured surfaces or finger grooves can be included. The explanation should mention comfort, control, and reducing hand fatigue.

Question 7: Describe the process of using a jigsaw to cut a curved shape in a piece of wood. Include safety tips.

Answer: The process involves securing the wood, selecting the appropriate blade, and guiding the jigsaw along the marked curve. Safety tips include wearing eye protection, using ear protection, and keeping hands away from the blade.

Question 8: Design a plan for assembling a small shelving unit using screws and brackets. Include the order of assembly and tools needed.

Answer: The plan should show the frame first, attaching vertical supports to the base with screws. Shelves are then fixed with brackets. Tools include a screwdriver, drill, and measuring tape. The order ensures stability and ease of assembly.
