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

On the other hand, none of the damage reach to the passenger compartment, the crumple zone did its job
Example of old car didn’t have crumple zone or Safety cell
Safety cell:
The Safety cell has crumple zone at both ends and a 'cage' in the passenger compartment. As the crumple zones absorb energy from crushing See figure (3.1), it helps the car slow down the impact and Safety cell prevent the rest of impact energy and crumple zone parts from entering the passenger compartment. Figure (3.1) how Mercedes Benz cars distribute the crash impact to chassis not to Safety cell were passenger are.
Safety cell made from Ultra High Strength Steel and high technique structure to save the passengers. Engineers have selected special materials even designs that make vehicles much safe. It very stronge against deformation so everythings inside Safety cell will be protacted from crush. Material are over 50% stronger than a 100 years ago, that’s help us to build Safety cell with high Specifications and Standards that serve our interests

Unlike lots conventional designs that care frontal crash energy simply to the lower force-bearing structures in the front end, the Advanced Compatibility Engineering (ACE) system actively displace front
In the lab of “The Falling Eggs and Automotive Lab”, we had to design a protective device able to hold the egg and allowing it survive from the impact of hitting the ground from the top of the staircase. We did this lab to investigate newton’s Laws and prove how they work. In the lab, we have to observe the forces that act on the egg and evaluate the way they work. We do this lab with an egg to relate to a real life collision with a car. The egg is essentially the person and the device that the egg is in is the Airbag. We use our knowledge about airbags and apply that to this lab in order to make the egg survive and not crack.

The aim of this report is to present the numerical analysis of human head response in a car accident in the sagittal plane. This is achieved by making oneself aware of the dynamic loading that arises at the instant accident occurs and the response of the human head to such loading. The response is usually biomechanical, which can be studied in terms of head acceleration due to the impact caused by the collision of the
Damaged or rusted guards offer virtually no protection at all. In addition, hitting one at an offset (with the front left or right side of your car) causes severe damage to the car and may demolish the area occupied by the driver or right front passenger. Finally, a high-speed collision with the side of a trailer, which lacks an underride guard, can shear off the top half of a car.
Crumple zones are designed to absorb the energy from the impact during a traffic collision by controlled deformation. This energy is much greater than is commonly realized. A 2,000 kg (4,409 lb) car travelling at 60 km/h (37 mph) (16.7 m/s), before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 14.2 m (47 ft) crashing on to a solid concrete surface. Increasing that speed by 50% to 90 km/h (56 mph) (25 m/s) compares to a fall from 32 m (105 ft) - an increase of 125%. This is because the stored kinetic energy (E) is given by E = (1/2) mass × speed squared. It increases by the square of the impact velocity.
Scheff’s Labelling Theory is a process which involves labelling people with mental disorders when they produce behaviour that does not fit with socially constructed norms and labelling those who reflect stereotyped or stigmatized behaviour of the ‘mentally ill’. A disadvantage of labelling an individual with depression is that labelling can accentuate and prolong the issue. In addition by labelling someone with depression who in fact is not depressed may in fact become depressed as a result. Another problem is that labelling an individual with depression means that they can have problems with getting a job and leading a life in the future because
In the novel “To Kill a Mockingbird” written by Harper Lee there are two important characters revealed to us throughout the text. These characters are are Boo Radley and Atticus Finch. These important characters are revealed to us through dialogue, actions and choices and finally through what others say about them. Atticus is a courageous and unprejudiced man with good values and morals. Boo Radley is misunderstood and with one selfless act the opinions from from the community are rapidly changed.
Article Analysis In the article titled, ’Free Speech’ and the 1st Amendment Aren't Always the Same Thing by Garrett Epps, Epps discusses the definition of the term “free speech” in the United States and how it is being viewed in other parts of the world. Epps’ goes to explain that the idea of free speech doesn't give one the authority to bash one’s racial or religious beliefs. The author goes on to argue that countries around the globe view the definition of freedom differently than of those in the United States.

Baxton Technology Company manufactures surface automotive hoists which are used by garages, service stations and other repair shops to lift cars for servicing. Because of its design, quality of workmanship, safety features, ease of installation and five-year warranty, Baxton Lifts achieved a reputation as the “Mercedes” of the hoist industry and is considered a leader in automotive lift safety in Canada and United States.
In a little over hundred years since automobile took hold of most people’s imagination, technologies design to make acceleration faster and reaching higher speeds have evolved. Despite charges, turbo charges, twin turbo charges or NOX, there are limits, which cannot be greater by land-based vehicle in terms of speed. Not the same can be said about the rather unseen parts of the automotive evolution. The only limitation to them is in connection with the human body ‘s ability to withstand rapid decelerations. It would be a lot easier to stop a car then to make it go faster otherwise. Whether they come in form of drum brakes or as disk, the brakes have been the horsepower’s companions throughout decades, each pulling
The modern solution is something called a roll-cage. A roll-cage is a specifically engineered frame that is located in the passenger side of any race car. The purpose is to protect the car's occupants from getting injured if they're bodies are to sway to that side in a crash.

Along with accidents not only comes a little headache or a broken bone, but injuries that stay with you forever such as whiplash and brain damage. Most brain damage incidents occur when you are involved in a side impact collision and the side of your head hits the glass (brain injury). Side impact airbags are just one of the many ways in which this type of life threatening injury can be avoided (whiplash). There is also whiplash, which hurls your head violently, and usually results in long term disability. Since whiplash is so hard to avoid, it can only be avoided by reducing the number of accidents on the streets. Also one of the most painful and most traumatizing injuries that we encounter in accidents are bone fractures, which occur in 65% of all accidents (Bush 11). So in turn by making these cars safer we can all avoid these painful, traumatizing, life-threatening injuries.
The safety car appears when an accident happens. Drivers must drive behind the safety car slowly and they cannot overtake each other. When someone doesn’t obey the rules he has a penalty. It means that he must take a few seconds pit stop.
