Understanding Speedometer Functionality

The video tutorial explains how a speedometer works using an animation. It identifies key components such as the dial, pointer, hairspring, spindle, stationary field plate, speed cup, and magnet. The arrangement of these components is detailed, highlighting the interaction between the magnet and speed cup, which is crucial for the speedometer's operation. The tutorial also covers the role of the hairspring in controlling the needle's movement and ensuring accurate speed readings. The video concludes with a call to action for viewers to subscribe and visit the website for more tutorials.

Which component of the speedometer is responsible for indicating the vehicle's speed?

• Spindle

• Hairspring

• Dial

• Pointer

What color is the speed cup in the speedometer animation?

• Green

• Red

• Blue

• Yellow

How is the magnet in the speedometer driven?

• By the speed cup

• By the hairspring

• Through a flexible coupling from the vehicle's transmission

• By the vehicle's engine

What is the relationship between the speed of the magnet and the vehicle?

• The magnet does not rotate

• The magnet rotates at the same speed as the vehicle

• The magnet rotates slower than the vehicle

• The magnet rotates faster than the vehicle

What causes the speed cup to rotate in the speedometer?

• Hairspring tension

• Direct connection to the vehicle's transmission

• Magnetic field produced by the rotating magnet

• Mechanical linkage with the magnet

What is the primary function of the hairspring in a speedometer?

• To drive the magnet

• To support the speed cup

• To control and limit the needle's movement

• To connect the spindle to the dial

How does the hairspring help when the vehicle stops?

• It disconnects the spindle

• It stops the magnet

• It brings the needle back to zero

• It accelerates the needle

What happens to the needle when the vehicle moves?

• It disconnects from the spindle

• It rotates the speed cup

• It moves to indicate the vehicle's speed

• It remains stationary

What is the purpose of the stationary field plate in the speedometer?

• To support the magnet

• To provide a reference for the speed cup

• To stabilize the spindle

• To indicate the vehicle's speed
