RESOURCES FOR TECHNOLOGY
2
Technological Resources

• Every technological process involves the use of
  seven resources
• People
• Information
• Materials
• Tools Machines
• Energy
• Capital
• Time

Technological Resources

• People
• People create technology and people consume its
  products and services
• Former USSR sent the first satellite, Sputnik,
  into space in 1957
• NASA was created in US in 1958 to direct the
  space program
• US astronauts landed on the moon in 1969
• People provide the labor on which technology
  depends
• People are also the consumer of the technology

Technological Resources

• Information
• Technology has grown quickly in the last few
  decades due to an explosion of information ---
  internet
• Information is used in different ways surgeon,
  engineer, farmer etc.
• Data --- raw facts and figures
• Data is collected, recorded, classified,
  calculated, stored, and retrieved --- it becomes
  information
• Data processing is the act of turning data into
  information
• Information can be found in computer files,
  books, films, and museums.

Technological Resources

• Materials
• Natural resources are materials found in nature
  --- air, water, land, timber, minerals, plants,
  and animals
• Raw materials --- natural resources that are used
  to make finished products
• Renewable raw materials are those that can grown
  and therefore can be replaced --- wood, natural
  rubber, animals and plants etc
• Nonrenewable raw materials --- oil, gas, coal,
  and minerals
• Limited and unlimited resources --- water, oil
  etc
• Synthetic materials --- nylon, acrylic, teflon,
  dacron, rayon and fiberglass
• Synthetics are not costly and often are more
  useful than natural materials --- glass, plastics

Technological Resources

• Tools and Machines
• Tools Extend Human capability
• Hand tools extend the power of human muscle
• Machines change the amount, speed, or direction
  of a force
• Simple machines provide a mechanical advantage,
  i.e. they multiply the force or distance we put
  into work --- page 32
• Electronic tools are used for testing electrical
  circuits.
• Optical tools extend the power of the human eye
  --- lenses, microscopes, telescopes and laser
• Lasers send very strong bursts of light energy
  that can be used to measure, cut, and weld
  materials
• It can also be used to repair damage in a human
  eye

Technological Resources

• Energy
• It is needed to move, to heat, to cool, to
  lighten
• Renewable energy sources human, animal muscle,
  wood
• Limited energy sources oil, coal, natural gas
  and nuclear fission
• Unlimited energy sources solar, wind,
  gravitational, tidal, geothermal and nuclear
  fusion
• Many forms of energy start with the sun
• Six different kinds of energy sources human and
  animal muscle power, solar energy, gravitational
  energy, geothermal energy, chemical energy and
  nuclear energy
• We can convert energy sources into mechanical,
  electrical, and light energy
• We can only change matter into energy or change
  one form of energy into another form

Technological Resources

• Capital
• Any form of wealth is capital --- cash, stock,
  buildings, machinery, and land
• To raise capital, a company may sell stock
• Investors become part owners or shareholders
• Company may turn back some of its profit to
  investors in the form of dividends
• Companies may take loan from a bank --- interest
• Time
• Early man measured time by sun rise and sun set
• Computers process data in nanoseconds (billionth
  of a sec)
