Question 1: Describe the primary purpose of a jigsaw in the manufacturing process. What types of materials is it best suited for?

Answer: A jigsaw is used for making curved or intricate cuts in materials such as wood, plastic, or thin metal sheets. It is best suited for detailed cutting tasks that require precision and flexibility.

Question 2: List three safety precautions that should be followed when using a power drill.

Answer: Wear safety goggles to protect eyes, secure the material firmly to prevent slipping, and ensure the drill bit is properly fitted before use.

Question 3: Explain the difference between a Philips screwdriver and a flat-head screwdriver. When would you use each?

Answer: A Philips screwdriver has a cross-shaped tip suitable for screws with a cross slot, providing better grip for torque. A flat-head screwdriver has a single flat blade, used for screws with a straight, horizontal slot. Use the Philips for cross-shaped screws and the flat-head for straight-slotted screws.

Question 4: Sketch a simple plan for a handheld tool that could be used to tighten small nuts and bolts. Include labels for the main parts.

Answer: A correct sketch would show a handle, a rotating shaft, and a gripping end with a socket or grip designed to fit small nuts and bolts. Labels should include 'Handle', 'Rotating shaft', and 'Socket grip'.

Question 5: Identify two differences between a saw and a file in terms of their function and typical use.

Answer: A saw is used for cutting through materials like wood or plastic, creating a new edge or shape. A file is used for smoothing or shaping edges by removing small amounts of material.

Question 6: Design a safety checklist for students using hand tools in a workshop. List at least five items.

Answer: Wear safety goggles, ensure tools are in good condition, work on a stable surface, keep fingers away from cutting edges, and use tools for their intended purpose.

Question 7: Sketch a cross-sectional view of a hammer showing the handle, head, and striking surface. Include labels.

Answer: A correct sketch would depict a hammer with a long handle attached to the head, which has a flat striking surface on one side and possibly a claw or wedge on the other. Labels should include 'Handle', 'Head', 'Striking surface'.

Question 8: Explain why it is important to select the correct tool for a specific task when designing a product.

Answer: Using the correct tool ensures efficiency, safety, and precision in the manufacturing process. It also helps prevent damage to the material or tool and results in a higher quality product.

Question 9: Plan and sketch a simple tool storage system for a student workshop. Include at least three different tool compartments or holders.

Answer: A well-designed sketch should show a storage unit with sections for hand saws, screwdrivers, and drills. Labels should specify each compartment, and the plan should consider accessibility and safety.

Question 10: Describe the function of a coping saw and what kind of cuts it is best suited for.

Answer: A coping saw is used for making intricate, curved cuts in wood or plastic. It is ideal for detailed shaping and fitting of joints.

Question 11: What are the advantages of using a cordless drill over a corded drill in a workshop setting?

Answer: A cordless drill offers greater mobility and ease of use, especially in places without power outlets. It is portable and convenient for quick tasks.
