6. What are the different types of suspension systems and how do they work?

Independent Suspension

• Each wheel is suspended independently, allowing for a smoother ride.
• It consists of a control arm, coil spring, and shock absorber.

Dependent Suspension

• The wheels on each axle are connected, which reduces manufacturing costs.
• It consists of a solid axle, leaf springs, and shock absorbers.

Air Suspension

• Uses air bags to adjust the ride height and stiffness.
• Provides a comfortable ride and improved handling.

7. What are the different types of steering systems and how do they work?

Rack and Pinion Steering

• The most common type of steering system used in passenger cars.
• Consists of a rack and pinion gear that converts rotational motion from the steering wheel into linear motion.

Recirculating Ball Steering

• Used in older vehicles and heavy-duty trucks.
• Consists of a recirculating ball that travels through a nut to convert rotational motion into linear motion.

Hydraulic Steering

• Uses hydraulic fluid to assist the driver in steering.
• Provides a smoother and lighter steering feel.

8. What are the different types of climate control systems and how do they work?

Manual Climate Control

• The driver manually adjusts the temperature, fan speed, and airflow direction.
• Uses a simple control panel with knobs or dials.

Automatic Climate Control

• Uses sensors to automatically adjust the temperature, fan speed, and airflow direction.
• Provides a more comfortable and consistent cabin environment.

9. What are the different types of tire construction and how do they affect vehicle performance?

Radial Tires

• The most common type of tire used in passenger cars.
• Have a flexible sidewall and a sturdy tread.
• Provide a smooth and comfortable ride.

Bias-Ply Tires

• Used in older vehicles and off-road applications.
• Have a less flexible sidewall and a more rigid tread.
• Provide a stiffer ride and better traction on rough terrain.

Tubeless Tires

• Do not have an inner tube.
• Are more puncture-resistant and can be repaired more easily.

10. What are the different types of vehicle body construction and how do they affect vehicle safety?

Unibody Construction

• The most common type of body construction used in passenger cars.
• The body and frame are integrated into a single structure.
• Provides good strength and rigidity.

Body-on-Frame Construction

• Used in trucks and SUVs.
• The body is mounted on a separate frame.
• Provides a stronger structure but can be heavier and less fuel-efficient.

Space Frame Construction

• Used in high-performance vehicles.
• Consists of a lightweight frame made of aluminum or carbon fiber.
• Provides excellent strength and rigidity with a reduced weight.
