The suspension part in this picture is a/an:
Correct Answer
B. Ball Joint
Explanation
The suspension part in the picture is a ball joint. A ball joint is a pivot point that connects the control arm to the steering knuckle. It allows for the smooth movement and rotation of the control arm, enabling the wheels to turn and absorb shocks while maintaining stability and control.
2.
The suspension part in this picture is a/an:
Correct Answer
C. Bushing
Explanation
The correct answer is Bushing because a bushing is a type of suspension component that is used to reduce friction and provide support between two moving parts. In the given picture, the suspension part appears to be a small cylindrical component that is inserted between two larger parts, indicating that it is likely a bushing. The other options, such as Steering Holder, Lower Arm, and Spring, do not accurately describe the component shown in the picture.
3.
The suspension part in this picture is a/an:
Correct Answer
D. Lower Arm
Explanation
The suspension part in the picture is a lower arm. The lower arm is a component of the suspension system in a vehicle and is responsible for connecting the frame or body of the vehicle to the wheel assembly. It helps to maintain the alignment and stability of the wheels, allowing for smooth and controlled movement of the vehicle.
4.
The suspension part in this picture is a/an:
Correct Answer
C. Knuckle
Explanation
The suspension part in the picture is a knuckle. A knuckle is a component of the suspension system that connects the wheel assembly to the suspension system. It allows the wheel to pivot and rotate, allowing for steering and movement of the vehicle. The knuckle is typically a sturdy and durable component, made from strong materials to withstand the forces and stresses of the suspension system.
5.
The suspension part in this picture is a/an:
Correct Answer
B. Stabilizer Bar
Explanation
The suspension part in the picture is a stabilizer bar. A stabilizer bar, also known as a sway bar or anti-roll bar, is a component of the suspension system that helps to reduce body roll and improve stability during cornering. It connects the left and right sides of the suspension together and helps to distribute the weight evenly. This helps to improve the handling and control of the vehicle.
6.
This type of suspension is better known as:
Correct Answer
D. Multi-Link with Trailing Arm
Explanation
The correct answer is Multi-Link with Trailing Arm. This type of suspension system is characterized by multiple links that connect the wheel hub to the chassis, along with a trailing arm that provides additional support and stability. The multi-link design allows for independent movement of the wheel, resulting in better handling, stability, and control. The trailing arm helps to control the vertical movement of the suspension and provides additional support during cornering and braking. Overall, the multi-link with trailing arm suspension is considered to be a more advanced and sophisticated design compared to other options listed.
7.
This type of suspension is better known as:
Correct Answer
C. Double Wishbone
Explanation
The correct answer is Double Wishbone. Double Wishbone suspension is a type of independent suspension system commonly used in vehicles. It consists of two wishbone-shaped arms that are attached to the wheel hub and the chassis. This design allows for better control of wheel movement, providing improved handling, stability, and comfort. Double Wishbone suspension is often found in high-performance and luxury vehicles due to its superior performance characteristics.
8.
This type of suspension is better known as:
Correct Answer
B. Multi-Link without Trailing Arm
Explanation
The correct answer is Multi-Link without Trailing Arm because this type of suspension system uses multiple links and control arms to connect the wheel hub to the chassis, providing better control and stability. Unlike the Multi-Link with Trailing Arm suspension, it does not include a trailing arm, which is a separate component used to locate the wheel. This type of suspension is commonly used in high-performance and luxury vehicles for its improved handling and ride comfort.
9.
In a front Double Wishbone suspension, which component allows the front steering knuckle to rotate on its axis?
Correct Answer
D. Ball Joints
Explanation
Ball joints allow the front steering knuckle to rotate on its axis in a front Double Wishbone suspension. Ball joints are spherical bearings that connect the control arms to the steering knuckle, allowing for smooth and controlled movement of the suspension. They provide flexibility and allow the wheels to move up and down while maintaining a stable connection to the control arms. This rotation is essential for the proper functioning of the suspension system and ensures efficient steering and handling of the vehicle.
10.
In a front MacPherson Strut suspension, which component(s) allows the front steering knuckle to rotate on its axis?
Correct Answer(s)
C. Bearing in the upper strut mount
D. Ball Joints
Explanation
In a front MacPherson Strut suspension, the component that allows the front steering knuckle to rotate on its axis is the bearing in the upper strut mount. This bearing provides a smooth and controlled rotation, allowing the steering knuckle to move freely and maintain proper alignment. Ball joints, on the other hand, are responsible for connecting the steering knuckle to the control arms and do not directly affect the rotation of the knuckle. The other components listed, such as the lower control arm, rubber bushings, and upper control arm, also play important roles in the suspension system but do not directly enable the rotation of the steering knuckle.
11.
Which component controls suspension oscillations?
Correct Answer
C. Dampers
Explanation
Dampers control suspension oscillations by absorbing and dissipating the energy generated during the up and down movement of the suspension. They help to regulate the motion of the suspension system, preventing excessive bouncing or rebounding. Dampers work in conjunction with other components like springs to provide a smooth and controlled ride, enhancing the stability and handling of the vehicle.
12.
What component allows the control arms to pivot at the body attachment points?
Correct Answer
D. The control arms do not move at the body attachment points
13.
Which of the following statements are true about subframes?
Correct Answer(s)
A. They isolate vibration and harshness from the rest of the body
B. They provide additional support and rigidity to the vehicle body
D. They contain suspension mounting points
Explanation
Subframes play a crucial role in a vehicle's structure. They provide additional support and rigidity to the vehicle body, enhancing stability and handling. They also contain suspension mounting points, which are essential for connecting the suspension system to the rest of the vehicle. Additionally, subframes help isolate vibration and harshness from the rest of the body, ensuring a smoother and more comfortable ride.
14.
In the event of high fluid demand at the rack, what component allows additional fluid to flow?
Correct Answer
B. Reservoir
Explanation
The reservoir is the component that allows additional fluid to flow in the event of high fluid demand at the rack. The reservoir stores excess fluid and supplies it to the system when needed. It acts as a buffer, ensuring that there is always an adequate supply of fluid available for the power steering system to function properly.
15.
What TPMS stands for?
Correct Answer
D. Tire Presure Monitor System
Explanation
TPMS stands for Tire Pressure Monitor System. This system is designed to monitor the air pressure in the tires of a vehicle and alert the driver if the pressure drops below a certain level. It helps to ensure that the tires are properly inflated, which can improve fuel efficiency, extend tire life, and enhance overall safety on the road.
16.
In a Michellin tire P225/50R16 87S : What percentage of the tire is the height?
Correct Answer
B. 50%
Explanation
In a Michelin tire P225/50R16 87S, the height of the tire is represented by the number 50. The question asks for the percentage of the tire that is the height, which is 50%.
17.
How do you adjust the toe?
Correct Answer
B. Through the tie rods
Explanation
The toe of a vehicle refers to the angle at which the tires point inward or outward when viewed from above. To adjust the toe, the tie rods are used. The tie rods are part of the steering system and connect the steering gearbox to the steering knuckles. By adjusting the length of the tie rods, the alignment of the wheels can be changed, allowing for the adjustment of the toe. This is typically done by a mechanic using specialized tools to ensure proper alignment and optimal tire wear.
