N-Level Technical and Vocational Skills 1 — Questions and Answers
Question 1: What is the first step before operating any electrical equipment in a workshop?
- Turn it on immediately
- Check that it is safe to use, properly maintained, and that you understand how to operate it (Correct answer)
- Ask a friend to operate it
- Ignore safety checks if you are in a hurry
Correct answer: Check that it is safe to use, properly maintained, and that you understand how to operate it
Before operating electrical equipment, always check it is safe (no damaged wires, correct voltage), properly maintained, and that you understand the operation procedure — safety first in all technical work.
Question 2: What does 'technical drawing' (or engineering drawing) communicate?
- Only the colour of a product
- The precise dimensions, shape, materials, and specifications of an object so it can be manufactured accurately (Correct answer)
- A rough sketch of ideas only
- The price of a product
Correct answer: The precise dimensions, shape, materials, and specifications of an object so it can be manufactured accurately
Technical drawings use standardised symbols, dimensions, and views to communicate exactly how an object should be made — ensuring anyone reading the drawing can manufacture it correctly.
Question 3: What is the purpose of a prototype in product design?
- To sell directly to customers
- To test whether a design idea works in practice before full-scale production (Correct answer)
- To replace technical drawings
- To be put in a museum
Correct answer: To test whether a design idea works in practice before full-scale production
A prototype is a working model of a product used to test, evaluate, and refine a design before committing to mass production — identifying problems early saves cost.
Question 4: What safety equipment should be worn when working with power tools?
- No protection is needed
- Appropriate personal protective equipment (PPE) including safety goggles, ear protection, and gloves where appropriate (Correct answer)
- Only a hard hat
- Only gloves
Correct answer: Appropriate personal protective equipment (PPE) including safety goggles, ear protection, and gloves where appropriate
Personal Protective Equipment (PPE) is essential when working with power tools. Safety goggles protect eyes from flying debris, ear protection reduces noise damage, and gloves protect hands from cuts.
Question 5: What is 'quality control' in manufacturing?
- Selling only expensive products
- The process of inspecting products during and after manufacture to ensure they meet specified standards (Correct answer)
- Making products as quickly as possible
- Reducing material costs only
Correct answer: The process of inspecting products during and after manufacture to ensure they meet specified standards
Quality control involves inspecting and testing products during and after manufacture to ensure they meet the required standards for safety, performance, and dimensions — detecting and correcting defects.
Question 6: What does 'tolerance' mean in technical/engineering contexts?
- Accepting poor quality
- The permitted range of variation in a dimension — how much a measurement can differ from the nominal value (Correct answer)
- The maximum weight a tool can carry
- The lifespan of a machine
Correct answer: The permitted range of variation in a dimension — how much a measurement can differ from the nominal value
Tolerance in engineering is the acceptable range of variation in a measurement. For example, a bolt of 10mm ± 0.5mm means it can be 9.5mm to 10.5mm and still be acceptable.
