#1
What is the primary purpose of Anti-lock Braking Systems (ABS) in vehicles?
To prevent wheel lockup during braking
ExplanationPrevent wheel skidding for better control and steering during braking.
#2
Which system uses radar technology to prevent collisions by automatically applying the brakes if an imminent collision is detected?
Automatic Emergency Braking (AEB)
ExplanationDetects potential collisions and applies brakes to prevent accidents.
#3
What is the function of traction control systems (TCS) in vehicles?
To prevent wheelspin under acceleration by controlling wheel slip
ExplanationRegulates wheel spin during acceleration to maintain traction and control.
#4
Which component is essential for a vehicle's suspension system to absorb shocks?
Shock absorbers
ExplanationDampens oscillations to provide a smoother ride and better handling.
#5
What is the primary function of a vehicle's 'crumple zones'?
To absorb and redistribute impact energy during a collision
ExplanationAbsorbs collision impact to protect passengers by dissipating energy.
#6
Electronic Stability Control (ESC) systems help vehicles to:
Prevent skidding during oversteering or understeering
ExplanationMaintain control by adjusting individual wheel braking to counteract skidding.
#7
Which of the following is used to measure the slip angle of a vehicle?
Gyroscope
ExplanationDetermines the angle between the vehicle's velocity vector and tire orientation.
#8
What role does aerodynamics play in vehicle dynamics?
Reducing air resistance for better fuel efficiency and stability
ExplanationEnhances fuel efficiency and stability by minimizing air resistance.
#9
The yaw rate in vehicle dynamics is a measure of:
How rapidly the vehicle is turning around its vertical axis
ExplanationAngular velocity around the vertical axis, indicating the rate of turning.
#10
What is the primary purpose of a differential in a vehicle?
To allow each wheel to move at different speeds
ExplanationPermits wheels to rotate at varying speeds for smooth turning and traction.
#11
Adaptive cruise control systems are designed to:
Adjust the vehicle's speed to maintain a set distance from the vehicle ahead
ExplanationAutomatically adjusts speed to keep a safe distance from the preceding vehicle.
#12
Tire load sensitivity refers to the phenomenon where:
The grip of a tire decreases as the load on the tire increases
ExplanationDecreased tire grip due to increased load, affecting handling and braking.
#13
In vehicle dynamics, 'roll moment' is best described as:
The rotational force that causes a vehicle to lean in a turn
ExplanationForce causing the vehicle to tilt or lean sideways during cornering.
#14
Active suspension systems in vehicles:
Automatically adjust the suspension settings for optimal ride comfort and handling
ExplanationContinuous adjustment of suspension components for enhanced ride quality and control.
#15
A 'Dual Clutch Transmission' (DCT) is known for:
Providing faster gear changes than traditional automatic transmissions
ExplanationUtilizes two clutches for seamless and quick gear changes.
#16
Which of the following best describes a 'Limited Slip Differential' (LSD)?
A differential that reduces slippage between two output shafts
ExplanationImproves traction by limiting speed difference between drive wheels.
#17
What is the primary benefit of using 'active aerodynamics' in high-performance vehicles?
To automatically adjust body parts for optimal aerodynamic efficiency
ExplanationEnhances performance by dynamically modifying vehicle aerodynamics.
