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.
