PCV CPC Case Study 25

-->
Tom, a newly trained driver, has started driving a different type of bus than he's used to. He must adapt to the new vehicle's dynamics, particularly understanding how forces like friction and gravity affect its operation. Tom's challenge is to ensure a smooth and safe journey for his passengers, considering factors like tyre condition, road surface, and vehicle weight.

There are 7 multiple choice questions in this PCV CPC case study. Read this carefully and ensure you fully understand the scenario before starting the test. You need to score 6 out of 7 to pass.

1. What happens during a vehicle skid in a turn, as Tom learns? Give one answer
A Becomes more stable
B Breaks away on the turn
C Consumes less fuel
D Increases speed
Correct Answer: B Breaks away on the turn
Explanation: A vehicle skids during a turn because it breaks away from its intended path.
2. How does road surface affect vehicle grip, in Tom's experience? Give one answer
A Changes the vehicle's speed
B Does not affect grip
C Influences the amount of friction
D Only affects tyre wear
Correct Answer: C Influences the amount of friction
Explanation: The type and condition of the road surface directly influence the friction and grip.
3. What effect does kinetic energy have on braking for Tom? Give one answer
A Converted into heat at brake pads
B Enhances tyre grip
C Increases fuel efficiency
D Reduces vehicle weight
Correct Answer: A Converted into heat at brake pads
Explanation: Kinetic energy is converted into heat at the brake pads during braking.
4. Why is smooth acceleration crucial in public transport, as per Tom's learning? Give one answer
A Decreases travel time
B Improves vehicle aesthetics
C Prevents passengers from being thrown backwards
D Reduces vehicle noise
Correct Answer: C Prevents passengers from being thrown backwards
Explanation: Smooth acceleration prevents passengers from being thrown backwards, ensuring safety.
5. What factor increases downhill speed in Tom's vehicle? Give one answer
A Engine power
B Gravity
C Tyre pressure
D Wind resistance
Correct Answer: B Gravity
Explanation: Gravity tends to increase a vehicle's speed on a downhill gradient.
6. How does sudden braking impact passengers, according to Tom? Give one answer
A Enhances safety
B Increases their comfort
C Reduces travel time
D Throws them forward
Correct Answer: D Throws them forward
Explanation: Sudden braking can throw passengers forward, posing a safety risk.
7. Why does Tom consider progressive braking important in buses? Give one answer
A Enhanced driver comfort
B Faster journey times
C Improved passenger safety
D Lower vehicle maintenance costs
Correct Answer: C Improved passenger safety
Explanation: Progressive braking primarily improves passenger safety and comfort.
