PCV CPC Case Study 24

-->
Emma, an experienced bus driver in a hilly region, often encounters varying road gradients and weather conditions. Her priority is ensuring passenger safety by understanding how different forces like gravity and inertia impact the bus's handling. She needs to adapt her driving style to manage the vehicle's kinetic energy effectively, especially when dealing with steep inclines, sharp corners, and diverse weather conditions.

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 influences a tyre's grip, as experienced by Emma? Give one answer
A The brand of the tyre
B The colour of the tyre
C The condition of the tyre tread
D The size of the tyre
Correct Answer: C The condition of the tyre tread
Explanation: The condition of the tyre tread significantly affects its grip on the road.
2. What can cause vehicle overturning, according to Emma's experience? Give one answer
A Constant speed
B Light vehicle weight
C Regular maintenance
D Sudden acceleration or braking
Correct Answer: D Sudden acceleration or braking
Explanation: Sudden changes in acceleration or braking can cause a vehicle to overturn.
3. How does gravity affect uphill driving for Emma? Give one answer
A Fuel consumption is reduced
B More engine power is needed
C Steering effort is decreased
D The vehicle becomes more aerodynamic
Correct Answer: B More engine power is needed
Explanation: Gravity requires more engine power to move a vehicle uphill.
4. Why does Emma value progressive braking? Give one answer
A Enhanced vehicle noise
B Improved safety and comfort
C Increased vehicle speed
D Reduced engine power
Correct Answer: B Improved safety and comfort
Explanation: Progressive braking primarily improves passenger safety and comfort.
5. In Emma's driving, what role does inertia play? Give one answer
A Resistance to change in motion
B The energy produced by the engine
C The speed of the vehicle
D The weight of the vehicle
Correct Answer: A Resistance to change in motion
Explanation: Inertia is the vehicle's resistance to changes in its state of motion.
6. What are the consequences of 'brake fade' for Emma? Give one answer
A Enhanced fuel economy
B Improved braking efficiency
C Increased tyre life
D Reduced braking effectiveness
Correct Answer: D Reduced braking effectiveness
Explanation: Brake fade' causes a reduction in braking effectiveness.
7. Why is avoiding harsh braking vital in a fully laden PCV for Emma? Give one answer
A Increases passenger capacity
B Leads to better fuel efficiency
C Reduces the risk of tyre wear
D Requires more effort to stop
Correct Answer: D Requires more effort to stop
Explanation: In a fully laden PCV, harsh braking should be avoided as it requires more effort to stop.
