Structure:
In this section we discuss how can we improve the force impact, improve the safety of passenger and reduce the weight.
Example:
Normal paper can’t carry heavy things, but by some Technique we can make it.
Safety cell and crumple zone:
According to a British Insurance Research study: 65% were in front impacts, 25% rear impacts, 5% left side, and 5% right side. So it is important to improve absorbing energy of impact force in front and rear vehicle by crumple zone, and protect passenger compartment by Safety cell.
Crumple zone:
crumple zones: front and rear areas of a vehicle that are create to deform and crumple during a traffic collision, by controlled the deformation,to absorb force without affecting the passenger compartment , The energy of crash is designed to travel through the vehicle to the back. This technique has been developed and invented by Mercedes-Benz in 1959 Designed by Daimler-Benz engineer Béla Barényi, The patent 854157.
He divided the vehicle body into three areas: the rigid non-deforming passenger compartment “Safety cell” and the crumple zones in the front and the rear. They are designed to receive the energy of an impact (kinetic energy) by deformation through collision
How it work:
It work by managing crash energy by absorbing it within the outside parts of the vehicle, instead being directly transmitted to the passenger compartment, This is accomplish by control the weakening of sacrificial outer elements of the vehicle, while strengthening and expanding the rigidity of the inner elements of the body of the vehicle
Engineers have to strike a balance in the midst of high impact resistance and low impact resistance. Simple designs can contain frame segments built to co...

...e assume the chassis was designed in one piece
In accident, this leads to the compression of the chassis on itself then on the passengers, so it make danger for them. Rather than unloading force of the impact on refraction point.

Sample example about if we change the structure we improve the hardness.
By logic sample half A4 paper can’t carry empty cup. If we use triangle civil engineer we can improve it to whole new level of hardness
Figure (4.5) show half A4 paper the next picture after we apply this method. Last picture prove that paper carry the cup perfectly.
How this stracture will be painfts to us
Mercedes-Benz prove "innovation in research vehicle ESF 2009" that we can improve the strength of pillars car or the whole safety zone cage by fold the car pillars structure figure (4.6).

In a car crash, the more weight there is, the risk of injuries drops (Williams, May Twenty-second, 2015). In most semi truck accidents (about seventy percent of semi truck accidents), when only the semi truck and trailer alone are involved, there are no deaths. But when another vehicle (such as a car, van, or pickup truck ) is involved, about ninety-eight percent of the time there is at least one fatality, which is really low compared to some other means of transportation (such as a train or an airplane) (EJustice, 2012).
Contemporary literature is the sharing of timeless truths that still hold relevance in our current society in a current manner. There is a saying “What has been will be again, what has been done will be done again; there is nothing new under the Sun.” (Ecclesiastes 1:9, n.d.). What the saying means is that anything we experience now has already been experienced and to believe that you have a fresh new idea, way of thinking, activity or anything than you are mistaken. Everything that can be thought of already has been. The story that I read during this session that reminds of this and has helped shape my view on contemporary literature is “Car Crash While Hitchhiking”, it was written by Denis Johnson. I’m going to explain how this story in
Since the invention of the automobile, there have been many great innovations within the industry. The suspension of the automobile serves as a good example of one of those innovations. Could you imagine riding around in your brand new Nissan Skyline GT-R, with the same suspension methods used to stabilize old horse and carriage buggies centuries ago? That would not serve its purpose very well. Due to the demands of society, vehicle stabilization became a priority to increase safety. Throughout the years, there have been different variations of vehicle suspension systems. For example, we have adaptive air, solid axle, and dead axle suspensions. Without the advancements made in the way we travel and transport goods, civilization could not prosper the way it has.
The crumple zone is an essential part of any car that provides safety for the passengers during collusion with another car or object. Without any form of a crumple zone, passengers would be much more likely to suffer from injury or possibly death. For this same reason, crumple zones have existed in cars for years and are still being improved to this day. One way you can better understand a crumple zone is by creating a scale model. My group and I have made multiple crumple zones with trial and error to better understand them and how they work.
Jay Scott Traylor was driving on a highway in North Carolina when his car struck a guardrail that was fitted with an ET-Plus end terminal. The terminal, manufactured by Trinity Highway Products, LLC, comprised three main components—an impact plate, guide channels, and an extruder head. When attached to the end of a standard guardrail, the unit was designed to absorb and dissipate crash forces by permitting the guardrail to be extruded through the unit’s head and flattened out into a ribbon. .

A tragedy is a wretched event that puts a person in despair. Tragedy is a genre which consists of continuous tragic happenings that ultimately lead to an unhappy ending. Arthur Miller expresses that what makes a tragic hero is their attempt to take fate into their own hands, which ends up being the reason for their ruin; while those who accept their fates tend to be the lucky and are spared a demise. Miller claims there are tragic consequences for a man who questions his position, regardless of whether he wants more or thinks he deserve less. The film, Crash, is an example of a tragedy, because one character tries to alter their own fate, and other characters have reservations of where they lie on the social spectrum.
Today, worldwide reports of the alarming road carnage statistics indicate that the same problem still persists as motorists continue to engage ...
There are three safety features in the egg project. The three safety features are seat belts, brakes, and airbags. The seat belts are made out of tape. The seat belts put pressure on the passenger. This means that it will keep the passenger inside the car instead of flying out and getting injured. The airbags are made out of bubble wrap. The bubble wrap will have a huge impact on the area of the passenger. It is like a soft cushion. This protects the passenger from hitting the passenger. The passenger will get hurt by the airbag, but not as much without one. If there wasn’t an airbag in a car, people would be getting into a second collision. A second collision is where the body hits the car. That is the whole point of an airbag. The brakes are made out of cotton balls. The brakes prevent the passenger from getting hit and it puts force on it. Also, they prevent it from getting into a first collision. A first collision is where a
During side impact crashes, cars can potentially flip. Side impact crashes are said to be the most dangerous type of car crash. The rear facing seat is the best option during this type of crash. If the car flips the sides of the seats are better equipped to harness the child in the seat. The seat is able to make pivoting motions because of the attachments to keep the child in a straight line. Keeping them in a straight line reduces the risk of injuries especially in the spinal cord.By having their back straight it won't bend or come close to snapping. A rear facing car seat protects the child by using a 5- point safety harness which is a system of hooks even used for race car drivers, and flight pilots.This allows the child to stay In the seat without them fal...
When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions. However, whenever a collision does occur, there is not much there to protect passengers in the rear of the car. Looking into this, there is evidence that shows that rear passengers do obtain injuries in collisions and pose the threat of contributing to others injuries. So, why are rear passenger airbags not standard in your vehicle?
The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in reasonable control.
Good stability and handling is achieved with a combination of suspension, steering, acceleration, brakes and weight distribution.
Knowing how to drive a car myself, I can’t expect an accident to occur. It just happens without your knowledge and sometimes without your fault too. It’s better to take precautions just in case such a thing happens. This will surely help you financially for the repairs of the vehicle.
Crumple zones- are a structural feature used in automobiles. They help by absorbing the impact; this is by spreading the impact through parts of the car instead of in the one spot. This reflects back onto law number one, two and three. This is shown when the car hits the object it causes the car to slow down or completely stop (1). The crumble zone would protect the driver because all the energy has been diverted around the car, instead of the one spot. As a result of the cars mass and its acceleration, the force can be calculated (2). When the car crashes it’s most likely that the object w...
We all use vehicles for transportation. People usually go to their desired destination either by driving their own cars or traveling in public transportation. Actually, it might be tough to choose that which one is the best selection for people to travel. Many people choose one of them according to their comfort while traveling and both of them have advantages and disadvantages in different conditions. Public transportation and driving own car both shares differences and similarities in many aspects, such as facility, cost, and comfort as well as traffic jam and accident occurrence.
