Global Engineering Challenges

There are global challenges that engineers face in society from ways to lessen our dependence to oil and protect the environment to ways to improve our surroundings and expand our reality and minds. A lot of these challenges will need engineers with vision and passion in order to come up with the solutions needed to improve the world around them. The three global challenges that will be covered in this paper are ways to lessen fuel consumption, how to restore and improve urban infrastructure and how to enhance virtual reality. These three global challenges reach into every part of the world and in every facet of society, which is why engineers are working on them now.

As a vehicle moves, the air moving around it creates a force called drag that acts in the opposite direction of its velocity. The role of engineers is to design vehicles that lessen drag as much as possible so it will use less fuel. Whether it be planes or cars aerospace engineers use different shapes to lessen the drag for as much as possible, for example for planes winglets on the end of wings are designed to reduce induced drag, while cars are designed with rounder smoother shapes so the air will flow smoothly around the vehicle shell. All three roles are different ways engineers can lessen fuel consumption but the best way is to incorporate all three roles into a design to maximize the efficiency and in some cases even eliminate the use of gas as a fuel.

The second global challenge an engineer will face is how to restore and improve urban infrastructure. With the population of the world getting larger, cities are getting more populated and the challenge for engineers is how to improve the urban infrastructure so cities keep work efficiently and things don't get too congested as populations grow. The first role of engineers would be to optimize urban space; this would entail making as much space as possible functional and having a purpose so as not to waste it. A great example of this is in Japan where the land is expensive so they have adapted to the space needed so not to waste space. Dr Matt Jameson an Architectural engineer at the University
