  1. TECHNOLOGY TOMPKINS

  2. WHAT IS TECHNOLOGY? • Computers are definitely a great technological advance for human beings, but they are NOT the only advance that we have made as a species. • Technology is a broad concept that deals with a species' usage and knowledge of tools and crafts, and how it affects a species' ability to control and adapt to its environment.

  3. WHAT IS TECHNOLOGY (continued)? • Technology is dynamic. • It is always changing, and always causing change. All the new different types and practices of technology are designed to improve upon existing technology, this is why we say technology is dynamic. LET’S SEE A FEW THINGS TECHNOLOGY HAS BROUGHT US…

  4. THE STEAM ENGINE • Steam engines built the foundation of the industrial revolution during the 1800’s. • Primary power source of locomotives up until the time of World War II, this technology completely changed mechanical ideas and theories. A very important invention.

  5. INTERNAL COMBUSTION ENGINE • Invented in 1876, now powers most land transportation vehicles. • Basic principle is to convert heat energy to mechanical energy, through a reciprocating piston powered by igniting a fuel. THIS TECHNOLOGY HAS ADVANCED…

  6. MOST POWERFULINTERNAL COMBUSTION ENGINES:2005 COMPETETIVE TOP FUEL RACING ENGINE • 7500Approximate peak output, in horsepower, of a competitive 2005 Top Fuel engine. That's almost 1000 horsepower per cylinder. • 12,654 Rpm the supercharger spins at maximum engine speed. With the engine at 8500 rpm, just turning the supercharger takes up 900 horsepower. • 77Gallons per minute the fuel system can pump at wide-open throttle. The engine will consume 22.75 gallons of fuel during warm up, burnout, staging, and the quarter-mile run. • 500Engine capacity, in cubic inches. The block and heads are CNC-milled from solid billets of aluminum, and the oil pan is titanium.

  7. THE ELECTRIC MOTOR • The most universally used source of power. • Average home has over 40 motors in it. • Based on the laws of magnetism and electromagnetism • Found in clocks, refrigerators, clothes washers/dryers, DVD/CD players, shavers, and many power tools, just to name a few.

  8. TECHNOLOGY IN MANUFACTURING • Hand Tools • Welding • Machining • Fasteners

  9. HAND TOOLS • Hammers • Wrenches • Hacksaws • Pliers • Clamps • Snips • Rulers/Measuring Tools

  10. WELDING • A Term for a number of processes used to join metallic and non-metallic materials. • Most common types: • SMAW (Shielded Metal Arc Welding) • GMAW (Gas Metal Arc Welding) • OAW (Oxyacetylene Welding)

  11. MACHINING • Machining refers to the process that is necessary to fabricate the majority of today’s products. It is difficult to name a product that does not require (either directly or indirectly), the use of a machine tool somewhere in the manufacture. • Machining tools include: Gages, Drills, Power Saws, Lathes, Milling Machines and thousands more. • CNC (Computer Numeric Controlled) Machining is a new form of machining technology.

  12. FASTENERS • Definition: Any device used to hold two objects or parts together. • Examples: • Threaded fasteners such as machine screws, machine bolts, cap screws, setscrews, acorn nuts, unfinished nuts, wing nuts etc. • Washers (standard and lock) • Keys • Cotter Pins • Rivets

  13. Computers • The heart of many modern information processing systems. • They are at every level of business life. • Manage many tasks previously held by humans. • Currently maintain several types of records, perform point-of-purchases, maintain air-fuel mixtures in engines, prepare layouts for advertising and even control machining tools. The tasks that computers are capable of handling are nearly endless.

  14. TECHNOLOGY EVOLUTION EXAMPLE:ENIAC • Short for Electronic Numerical Integrator And Computer • It was the first large-scale, electronic, digital computer capable of being reprogrammed to solve a full range of computing problems • It was unveiled on February 14, 1946, having cost almost $500,000. • 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and around 5 million hand-soldered joints. It weighed 30 short tons (27 t), was roughly 8 feet (2.4 m) by 3 feet (0.9 m) by 100 feet (30 m), took up 1800 cubic feet

  15. AND TODAY, THIS IS THE ENIAC EQUIVALENT: • This is a 2”x2” chip.
