Question 8: Discuss the factors to consider when selecting a tool for cutting different materials such as plastic, wood, and metal.

Answer: Consider the material's hardness, thickness, and type; the tool's cutting edge design, blade or bit type, and power source; and safety and precision requirements.

Question 9: Create a step-by-step plan for using a hand saw to cut a piece of timber to a specified length.

Answer: 1. Measure and mark the cut line on the timber. 2. Secure the timber firmly using clamps. 3. Align the saw blade with the mark. 4. Use steady, controlled strokes to cut along the line. 5. Check the length and smooth the edge if needed.

Question 10: Explain how to maintain and care for hand tools to ensure they remain effective and safe to use.

Answer: Clean tools after use, sharpen blades regularly, store in a dry place to prevent rust, and check for damage or wear before use.
