Mechanical engineering involves engineering, physics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery. There are many mechanical engineers that have created safety in automotive vehicles. There has been three big strides in innovation starting with seat belt, then transferring into airbags, and now autonomous sensory driving. These inventions have saved lives and prevented injuries which has made a big impact in our world. The use of seat belts in automobiles did not begin until the mid to late 1950's. Even then, seat belts were considered optional equipment. “In 1955, Swedish automaker Volvo was…show more content…
One way engineers develop their products effectively is through testing. “About 90 percent of 1994 model-year cars have at least a driver-side air bag. Moreover, automobile-industry analysts predict the total number of “airbag systems will exceed 40 million by 1996, a worldwide market of $6.6 billion. Domestically, the US. Congress and the National Highway Traffic Safety Administration adopted a rule last September requiring air bags for both the driver and front passenger in all cars by 1998 and in all trucks by 1999.” The real question is do these air bags work effectively. The answer is yes they do “ 24 percent fewer fatalities than expected in front and front-angle crashes (10 to 2 o'clock) of air bag-equipped cars. While the study found that air bags do cause some injuries--mostly abrasions, cuts, bruises, and burns--it also concluded that these are minor compared to the major injuries the bags prevent.” The invention of the airbag is credited to the German engineer Walter Linderer, and to the American John W. Hetrick who in 1951 registered for the first of his airbag patents. At first he just created a safety pillow for infants because of a tragedy that happened within his family and then innovated into the…show more content…
These three milestones: seat belts, air bags, and autonomous sensory driving have saved many lives. The future for automotive safety is very bright considering all the huge innovations in this topic. Mechanical engineers have made such a big impact in Danvers because it has prevented so many injuries. One mechanical engineer who has made probably the biggest impact is Nils Bohlin. The reason he started this in the first place was because he lost his family member in a car accident. We need mechanical engineers to keep innovating to create a safer environment for
