Below are some typical questions that students might encounter, along with well-explained answers to aid understanding.Question 1: What are the main safety rules to observe in a workshop?
Answer:
- Always wear appropriate personal protective equipment (PPE) such as safety goggles, gloves, and aprons.
- Keep the workspace clean and free of obstructions to prevent accidents.
- Handle tools and equipment carefully, following proper procedures.
- Switch off electrical tools when not in use.
- Report any damaged tools or equipment immediately.
- Do not wear loose clothing or jewelry that could get caught in machinery.
Question 2: Name three types of hand tools used in carpentry and their uses.
Answer:
- Hammer: Used for driving nails into wood or other materials.
- Screwdriver: Used for screwing or unscrewing screws.
- Chisel: Used for carving or cutting wood or other materials.
Question 3: Explain the function of a resistor in an electrical circuit.
Answer:
A resistor is a passive electronic component that limits or regulates the flow of electrical current within a circuit. It provides resistance, which helps control voltage and current levels, protecting other components and ensuring the circuit operates safely and efficiently.
Question 4: What is the purpose of a pulley in mechanical systems?
Answer:
A pulley is a simple machine used to change the direction of a force applied to lift or move loads. It can also reduce the effort needed to lift heavy objects by providing a mechanical advantage, especially when used in combination with other pulleys in a system.
Question 5: Describe the difference between a series and a parallel electrical circuit.
Answer:
- Series Circuit: Components are connected end-to-end in a single path. If one component fails, the entire circuit is broken. The total resistance is the sum of individual resistances, and current remains the same throughout.
- Parallel Circuit: Components are connected across the same voltage source, forming multiple paths for current. If one component fails, others can still operate. The total resistance decreases as more branches are added, and voltage across each component is the same.
Question 6: What are the basic symbols used in electrical wiring diagrams?
Answer:
- Battery: Usually represented by a pair of lines, one longer (positive) and one shorter (negative).
- Resistor: A zigzag line.
- Switch: A break in a line with an open or closed gap.
- Bulb: A circle with a filament symbol inside.
- Wire: Straight lines connecting components.
Question 7: List three types of simple machines and their functions.
Answer:
- Lever: Used to lift or move loads with less effort by applying force at a different point.
- Pulley: Changes the direction of force and reduces effort needed to lift loads.
- Inclined Plane: Allows heavy objects to be moved upward with less force over a longer distance.
Question 8: Why is it important to interpret technical drawings correctly?
Answer:
Interpreting technical drawings accurately is crucial because it ensures that the components and systems are built or assembled correctly. It helps prevent errors, saves time, and ensures safety during construction or maintenance processes.
Question 9: How does technology impact our daily lives?
Answer:
Technology affects daily life through innovations such as communication devices, transportation, healthcare, and household appliances. It makes tasks easier, faster, and more efficient, while also creating new opportunities for learning and employment. However, it also necessitates responsible use to mitigate negative impacts.
Question 10: What are the basic safety precautions when handling electronic components?
Answer:
- Ensure the power supply is disconnected before working on electronic devices.
- Handle components with dry hands to prevent electric shocks.
- Use proper tools like insulated screwdrivers and soldering irons.
- Avoid static discharge by grounding yourself or using anti-static mats.
- Work in a well-ventilated area, especially when soldering.
