MECHANICAL ENGINEERING
• What does it study?
• Examples of industries where mechanical engineer can work
• One study of case
MECHANICAL ENGINEERING
• Is a diverse subject that derives its breadth from the need to designand manufacture everything from small individual parts and devicesto large systems.
MECHANICAL ENGINEERING
• There are three main different areas of emphasis in mechanicalengineering:
1) Thermal fluid applications
2) Machine and product design
3) Materials science and processing
MECHANICAL ENGINEERING
Thermal fluid applications
• Thermodynamics, fluid dynamics, hydraulics, and heat transfer
• Design of energy production systems, heat exchangers, refrigeration,heating and cooling of buildings, pumps, compressors, airplanes,spacecraft, automobiles and others.
MECHANICAL ENGINEERING
Machine and product design
• This area has to do with the design of any kind of machine or machinecomponent, such as automobiles, airplanes, biomedical devices, etc.
• An important aspect of this area is the use of CAD, or ComputerAided Design.
MECHANICAL ENGINEERING
Materials science and processing
• Mostly concerned with the selection or creation of materials that areappropriate for the situation based on needed properties
• For example, design of strong lightweight composite.
MECHANICAL ENGINEERING
• Mechanical engineers play a central role in several industries such as:automotive, aerospace, biotechnology, computers and electronics,energy conversion, environmental control, automation,manufacturing.

Applied fluid dynamics: Tacoma Narrows Bridge
MECHANICAL ENGINEERING
• In the United States, state of Washington
• November 7, 1940
• Wind conditions: 40 mph (64 km/h)
• Cause of failure: 1. Forced resonance
2. Aeroelastic flutter
• No human life was lost in the collapse of the bridge.
• A dog was the only fatality of the Tacoma Narrows Bridge disaster.
