- 1. Engineering and Manufacturing David Andrade MS - Education BS – Mechanical Engineering (Aerospace)
- 2. What is an Engineer? Uses science and math to solve people’s problems Creates and invents new things Improves and makes things better
- 3. Engineering – what is it?
- 6. What Does it Take to Become an Engineer? Curiosity Creativity Like to figure things out, solve problems Enjoy learning --- stay in school Take math classes (at least pre-calc) Take science classes (Bio, Chem, Physics) Take CAD or other Technology courses Four year college engineering degree
- 7. Why be an engineer? Fun Help people; improve lives Solve real world problems Variety of applications, projects Contribute to society Lots of opportunities High demand for engineers Large and small companies, universities, non profits Rewarding Career Innovative thinking, and you get paid! Sikorsky Aircraft – new engineers are making $65K + /yr Provides a very strong background for other careers Potential for advancement to management

- 16. Summary Manufacturing is our country’s future and foundation for it’s economy The US manufactures a huge percentage of products, specifically high technology, high quality parts and devices The US is also know for it’s assembly work There is a shortage of engineers and manufacturing technicians Huge need, huge potential, high pay, high rewards If you like science, designing, creativity, math, working with your hands or building things, you should go into engineering or manufacturing
- 17. Amazing Engineering Feats Mr. Andrade Central High School
- 18. Amazing Runway New airport runway on the Portuguese island of Madeira . The airport's runway has a length of 2781 meters, (9000 ft) of which 1000 (3000) are supported by 180 pillars, each pillar 50 meters in length (about 17 floors). The runway is designed to accommodate 747s. Note the cars parked below the runway. The 2nd picture best shows how high it is -- and let's not even think about running off that runway!
- 23. Hiding Lockheed during WWII Lockheed During WW.II (unbelievable 1940s pictures) This is pretty neat--special effects during the 1940 's. During World War II the Army Corps of Engineers needed to hide the Lockheed Burbank Aircraft Plant to protect it from Japanese air attack. They covered it with camouflage netting to make it look like a rural subdivision from the air.

- 43. Smart Phones
- 44. The bridge (or should it be called tunnel) goes under water to allow movement of ships . In order for ships to pass, this bridge is half under the water. You drive down in the water and then come out on the other side. Truly a marvelous piece of engineering! This bridge is between Sweden and Denmark . The picture was taken from the Sweden side.
- 47. schlieren photography, which takes an invisible phenomenon and turns it into a visible picture Schlieren is German for “streaks”; in this case it refers to regions of different densities in a gas or a liquid, which can be photographed as shadows using a special technique. “In my lab we use this technique a lot,” Dr. Settles said. “Often it’s used for other things, like in supersonic wind tunnels, to show shock waves around high-speed aircraft.” The process involves a small, bright light source, precisely placed lenses, a curved mirror, a razor blade that blocks part of the light beam and other tools that make it possible to see and photograph disturbances in the air. In the world of gas dynamics, a cough is merely “a turbulent jet of air with density changes.” New York Times, Science Section, 10-2008. Downloaded from www.nytimes.com/science on 10-30-2008
- 48. A cough
- 49. A simulated explosion in a full- scale mockup of an airplane cabin, with departmen t store mannequin s. The photograp h captures the flash of the explosion and the shock wave that it sent through the cabin.
- 52. A revolver being fired. Gases originate first from the cylinder and then the muzzle of the firearm. The gases that envelop the hand of the shooter leave gunpowder residue behind.
- 53. A small firecracker explosion. The bright flash is a result of the cardboard shell of the firecracker blowing out both ends. The smoke is from the burning fuse, and the string suspends the firecracker from above.
- 56. A water strider, an insect that walks on water and can carry 15 times its body weight and stay afloat.
- 57. An Airedale dog sniffing a small flower, which was warmed to help make the airflow visible.
- 58. Engineers “Scientists study the world as it is. Engineers create the world that has never been.” Theodore von Karman
- 59. Your Turn Over the weekend, start thinking about a product or technology that interests you. Think about how it works, how physics is applied to it, and how you might make it better. We will be starting a project on this when we come back.
