The Car Safety Movement started in the late 1950’s/1960’s and it still continues now. The car safety movement has saved lives.
When you do the safety movement thing you always need to remember to put your seatbelts on. If you don’t put on your seatbelt it is a possibility you can fly out if you get into a accident or die. So for your safety you may always put on your seatbelt so you will remain seated at all times. If you get into a accident you won’t fly out because you will be locked in you will be protected if you get into a car accident with a bus or a truck then you might fly out or the airbag might help you stay alive when we have a accident make sure that you are safe with your safety rules. The safety movement has saved million of lives in the United States of America. The person who invented seatbelts is an english engineer George Cayley. And it began in the 19th century. In the safety and made it available to other car manufacturers for free while providing a method of limiting this movement in the event of a crash. A seatbelt functions to reduce the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with terior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag and by preventing occupants by ejected from the vehicle rolls over. The drivers and are traveling at the same speed as the car. If the car suddenly stops or crashes. Claire Straith was the first hero of the auto car safety movement. He was the first to recognize that it was a automobiles that injured people. An accident was just the event, but it was the collision between the passengers and the inside of the car that caused the injuries. Dr Straith was a pioneer of automobile safety. He described the cranial and facial injuries created by the dashboards and windshields in case of a car crash advocated the use of seat belts. and padded dashboards. Dr.Straith gained the attention of Walter P Chrysler and the knobs and handles of the 1937 dodge.
CAR TEST DUMMIES
Car test dummies are a full scale anthropomorphic test devices that simulate the dimensions, weight proportions and articulation of the human body, and are usually instrumented to record data about the dynamic behavior of the ATD in simulated vehicle impacts. This data can include variables such as velocity of impact,crushing force, bending, folding, or torque of the body, and deceleration rates during collision for use of in car tests. The more advanced dummies are sophisticated machines designs to behave as a human body and with many sensors to record the forces of an impact; they may cost over $400,000. For the purpose of the U.S regulation and Global Technical Regulations and for clear communication in safety and seating design. Dummies carry specifically designated reference points, such as the H-point; these are also used for examples automotive design. Crash test dummies are indispensable in the development of and ergonomics in all types vehicles, from automobiles to aircraft.
AIRBAGS…
An airbag is a vehicle safety device. it is an ocTo enable screen reader support, press
occupant restraint system consisting of a flexible fabric envelope of cushion designed to inflate rapidly during an automobile collision. it’s purpose is to cushion occupants during a crash and provide protection to their when they strike interior objects such as the steering wheel or windows. Modern vehicles may contain multiple airbag modules in various side and frontal locations of the passengers seating positions, and sensors may deploy one or more airbags in a impact zone at variable rates based on the type, angle and severity of impact; the airbag is designed to only inflate in moderate to severe frontal crashes. Airbags are normally designed with intention of supplementing the protection of an occupant who is correctly restrained with a seat belt. most designs are inflated pyrotechnic means or can be operated once. Newer side-impact airbags modules consist of compressed air cylinders that are triggered in the event in a side impact vehicle impact. The first commercial designs were introduced in passengers automobiles during the 1970’s with limited success. Broad commercial adoption of airbags occurred in many markets during the late 1980’s and early 1990’s with a driver airbag, and a front passenger airbag as well on some cars; and many modern vehicles now include four or more units.
BRAKES…
A brake is a mechanical device which inhibits motion,slowing or stopping a moving object or preventing it’s motion. the rest of this article is dedicated to various to various types of vehicular brakes. most commonly brakes use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat,though others methods of energy conversions may be employed. for example regenerative braking converts much of the energy to electrical energy,which may be stored for later use. other methods convert kinetic and potential energy in such stored forms as pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin , or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transforming the energy to rotating a flywheel. Brakes are generally applied to rotating axles or wheels, but may also take other forms such as the surface of a moving fluid (flaps deployed into water or air). some vehicles use a combination of braking mechanism, such as drag racing cars with both wheel brakes and a parachute, or airplanes with both wheel brakes and drag flaps raised into the air during landing. Since kinetic energy increases quadratically with velocity (K=mv2), an object moving at 10 m/s has 100 times as much energy as one of the same mass moving at 1 m/s, and consequently the theoretical braking distance, when braking at the traction limit, is 100 times as long. in practice, fast vehicles usually have significant
