Coil Springs in a Suspension System
Next to the engine and speed, the suspension system is important when it comes to cars. The suspension system serves two purposes. First, they contribute to the car's handling and braking for safety. Second is they keep passengers comfortable from bumps and other vibrations. A vehicle's suspension system is composed of different parts. One of them is the springs.
For the Swedish automaker, Volvo, safety and quality are key factors in manufacturing automobiles. For some of their vehicles, the company uses Volvo coil springs. It is actually the most common type of spring. They are also known as a helical spring because they are formed into the shape of a helix or spiral. Volvo coil springs are usually made of elastic materials that compress and expand to absorb the motion of the wheels.
There are actually two types of coil springs. There are tension coil springs which are designed to resist stretching. They usually have a hook or eye form at each end for attachment. There are also compression coil springs designed to resist being compressed.
The production of coils springs are not easy. Many of them are first wound in an annealed condition and then tempered to achieve some strength. After some time, this tempering can be lost and the spring will sag because it can no longer withstand the loads applied. But they can be re-set by returning them to their original length or setting them to a different length. Cutting the end of a car suspension spring to lower its height can cause some damage to the suspension system making it work inefficiently.
The suspension system is vital to any vehicle. The presence of Volvo Coil Springs also make the system work more effectively. A fast car without a good suspension will be very uncomfortable, not to mention the potential hazards it creates for the passengers.

Would a car's ignition coil be good for causing a corona discharge? If not what else can be used?
I am working on a science fair project and I need to form a corona discharge in a running car, I looked for neon transformers but they only go up to 9.5 kV which I don't think is enough. So I am stuck in transformer and I got a limited time. Thanks for your help
Sure. The spark of an automobile spark plug is essentially a corona discharge. Also, when you have a worn sparkplug wire in a car, you can sometimes get a corona discharge to a nearby metal surface.
If you take a car ignition coil and 12 volt DC source you can generate a high voltage.
You need to make and break the low voltage connection repeatedly to get the coil to work. Just connecting a steady dc voltage to the coil and letting it sit will not get you an output, and may even destroy the coil's primary winding.
You can use a relay that is connected to a pulse generator with enough power to close the relay. If you experiment with the pulse rate, probably between one and 100 Hz you shouldget some good results.
You could even try and old fashioned electromechanical buzzer in series with the battery and low voltage coil side. This will actually make and break the current flow as the buzzer is operating.
The ground side of the coil is most likely common to both the high and low voltage side of the crcuit, and may be the outer casing of the coil assembly.
Use a car spark plug wire as your conductor for the HV side. The insulation from any regular wire is probably not good enough to insulate the high voltage. You might as well try using a park plug also to see if you have it working. The Threaded section of the plug should be connected to the coils common side.
WARNING!!! BE exteremely careful when experimenting with this. The HV side can cause a serious shock and burn hazard, and posiibly death!
Good luck!
