Technically speaking a shock absorber can be defined as any mechanical device that on receiving a shock impulse smooths it out and converts it into kinetic energy. It can either absorb or dissipate the energy.
In general, it is a common device used in automobiles and airplanes to minimize the effect of a shock impulse. It is an important constituent of a vehicles suspension and it allows the vehicle to travel smoothly on a rough ground and on bumpy surfaces and provides a comfortable ride.
Other Applications Of A Shock Absorber
Shock absorbers are used for many purposes and are not only restricted to a car suspension. They are of different shaped and sized for many purposes like:
- the landing gear of an aircraft
- in many important industrial machines
- In buildings and bridges to make them resistant towards earthquake shocks.
Types of Shock Absorbers
Based on their mechanism and usage, there are various types of shock absorbers. Below given are a few types of shock absorbers:
Air Shock Absorbers
The air shock absorber consists of an air chamber, an iron piston and a fluid. Together these work to give an excellent shock absorber that aids the suspension springs of a vehicle. The presence of compressed air in it makes it a stiff shock absorber.
The air shock absorber is a load-adjustable shock absorber as it lessens the burden of any load on the suspension.
In some air shock absorbers, a rubber cylinder is also used to aid the function of the suspension springs.
The air chamber of the shock absorber consists of a valve that can be used to adjust the pressure inside the gas chamber.
Air shock absorber is a commonly used air absorber and it provides a smooth and a comfortable ride of a vehicle. Other than cars, this shock absorber is also used in the engines of high-speed boats.
Damper Shock Absorber
A damper shock absorber consists of a single or two chambers; it may be fluid filled or filled with air. It is commonly used to absorb the shock during the linear motion of a vehicle.
The damper shock has a configuration that can be adjusted and the presence of valves allows the increase or the decrease of the force capacity by letting the gas or the fluid out.
A damper shock absorber is of different types. While choosing a damper for a vehicle few factors must be kept on mind.
Below given is an example of a damper:
- Mono Tube Shock Absorber
The mono tube damper consists of single tube with two valves. It is mostly oil filled and used in larger vehicles.
When the damper compresses when of the valve gets opened and when it extends the other valve gets open and the first one closes. The amount of the fluid released depends on the speed of the bumps it gets while moving.
If it receives low speed small bumps the larger vents get opened and there is large amount of fluid is released. On the other hand if gets high speed strong bumps the smaller vent gets opened and a small amount of oil is released.
Twin Tube Shock Absorber
The twin tube shock absorber consists of two tubes and valves. One of the two valves has a piston rod and is fitted to the outer tube while the second valve is fitted into the inner tube.
The inner tube is smaller in diameter and handles the bump control of the vehicle and the outer tube which has the piston fitted valve handles the rebound control.
When the twin tube damper gets a shock through bumps the fluid inside tubes is forced towards the outer reservoir.
The presence of two valves and tubes makes it an effective shock absorber but the only problem with this shock absorber is that it can only work when there is a limited space to work in.
Spring Shock Absorber
The spring shock absorber uses the effect of a spring to absorb the shocks.
The tighter the spring coil will be the stiffer the shock absorber will be.
The spring shock absorber is fluid filled and the centre of the shock absorber consists of a rebound unit.
Types Of Bridges
A bridge is a structure which is built to link two areas of land over an obstacle such as a valley or a body of water like rivers, lakes and oceans.
Types Of Energy
For any work to be done by any object energy is required. Energy basically is defined as the capacity to do work.
A thin, sheet of film that is transparent is applied to your car’s windows in this simple procedure. There are many benefits of having your car or truck windows. The thickness of the film ranges from 0.001 to 0.004 inches and made of a different. Window tinting can also create hazards, especially for drivers at night. To ensure safety, many jurisdictions have enforced laws that are based on the darkness of the tinting films. For example, in Arkansas, the tint limit is twenty-five percent but in New Jersey, it is seventy-percent.
The three ways of window tinting include
• Film tinting-this is an inexpensive and simple way to tint your windows. The film applied to your window glass is found in different tints like metallic, mirrored, and flat. Some experts in the automotive field say this type of window tinting can help prevent the shattering of window glass in an auto accident. Although this may be true, it is generally helpful during the first months of applications. This is because the window tinting file can easily peel or crack.
• OEM tinted glass-with this type of window tinting the tint is added when the glass is prepared instead of applying it to the window. This type has a tint that is lighter and to replace it can be expensive.
• Coated tinting-in this technique a distinctive solution is applied to the window surface. It is often used as a spray. When tinting your windows this is the most effective way. It should only be done by an expert, as it is a difficult process to apply.
Benefits of window tinting
• Better driving-if the sun is in your face when driving it can be an annoyance but it can also be deadly. Having your windshield tinted will prevent glare from extreme sunlight and helps to shield your eyes.
• Privacy-not only does it offer some protection by preventing people from seeing in your car and it also protects things inside your car from being seen by others when you are not around. You will not need to store your valuables in the trunk to protect them from being stolen.
• Protects your car upholstery-UV rays and the heat from direct sunlight can help to keep the interior of your car from getting so hot that it cracks, fades, or warps your plastic dash and other plastic in your car. It also blocks as much as 90% of the harmful UV rays.
• Keeping cool—if you have the right window tinting you can help to reduce the heat inside of your car in the summer up to 60%.
• Staying healthy-window tinting can reduce the number of UV rays, which can cause skin cancer.
