B. Helmet
C. Ear muff
D. Apron

Answer: A. Safety goggles

SECTION B: Theory Questions

1. Define an alloy and give two examples.
Answer:
An alloy is a mixture of two or more metals, or a metal and another element, to improve strength, durability, or resistance. Examples:

Brass (Copper + Zinc)
Bronze (Copper + Tin)

2. Explain three (3) differences between hot working and cold working of metals.
Answer:

Hot working is done above recrystallization temperature, while cold working is done at or below room temperature.
Hot working improves ductility, while cold working increases hardness.
Hot working reduces strength, while cold working improves strength through strain hardening.

3. With neat sketches, describe a lathe machine and state two operations it can perform.
Answer:

Sketch: A lathe showing headstock, tailstock, carriage, and tool post.
Operations: Turning, facing, drilling, threading.

4. State four (4) safety rules that should be observed in the workshop.
Answer:

Always wear protective clothing and goggles.
Keep floors free from oil and water spills.
Switch off machines after use.
Do not operate faulty equipment.

SECTION C: Practical Question

Question: Draw and label a well-detailed sketch of an arc welding setup.

Expected Answer: A neat drawing showing:

Welding machine
Electrode holder
Workpiece
Cables
Ground clamp
