Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






2. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






3. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






4. Stored energy or energy at rest.






5. A circuit in which electricity flows along a single path to more than one device.






6. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






7. The path by which a message travels from the sender to receiver.






8. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






9. The process of turning abstractions of thought into concrete ideas.






10. A circuit in which electricity flows along more than one path.






11. Energy in motion.






12. The use of computers in each stage of the design process.






13. The formal rules that guide the design process.






14. A language - used to write computer programs - that can easily be translated into machine language.






15. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






16. A group of people working together to accomplish a common goal.






17. A device capable of detecting (sensing) changes in its environment; light and movement are examples.






18. The use of lasers to record realistic images of three- dimensional objects.






19. The long term storage mechanism of a computer. It holds the computer programs used for word processing - playing games - and other tasks.






20. The judgement of the end result based upon given criteria.






21. A popular movement.






22. The capacity to do work or exert effort.






23. The law that states that if the pressure of a gas increases - the volume decreases (provided that the temperature remains constant).


24. A device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.






25. The comparison of the amount of goods produced (output) to the amount of resources (input) that produced them






26. The passage of electric current through an electrolytic fluid for the purpose of separating molecules.






27. The path by which electric current or pulses flow.






28. Studying the effects of a given technology to determine its impact.






29. The superimposition of sine waves on electromagnetic carrier waves.






30. The field of knowledge relating to materials as they exists on a molecular or atomic level.






31. A device that orbits the Earth and receives messages from one location and transmits them to another.






32. Processes and knowledge that can be used to extend human abilities as well as satisfy human needs and wants.






33. The measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.






34. A method of obtaining energy from waste products






35. Current flow in which electrons move in only one direction.






36. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






37. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






38. The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.






39. The money a business makes after all expenses have been paid






40. Standards that a product must meet to be accepted.






41. The basic framework of a system






42. The use of simple machines to multiply the output force of a mechanical system.






43. Trade of products and services on a global scale.






44. In a computer - the primary circuit board to which all internal componnets are connected either directly or indirectly.






45. The use of pressurized liquid or gasses to control and transmit power.






46. The knowledge - tools - machines - skills - and other things that people make and do to send and receive information.






47. A resource that is entered into a system.






48. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






49. A production process in which the part or product moves down a line from one station to the next while parts are added.






50. The use of a computer system to produce technical drawings and/or design a product.
