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






2. A method of obtaining energy from waste products






3. 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.






4. The basic framework of a system






5. 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.






6. The number of waves that pass through a given point in one second. It is commonly measured in a unit called hertz. 1Hz is equal to one complete wave cycle in one second.






7. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






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






9. The act of putting different things together to form a new product or idea.






10. Someone who starts a business.






11. 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.






12. The capacity to do work or exert effort.






13. A unit that collects waves and decodes information contained within those waves.






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






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






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






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






18. Creating things through the process of planning.






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






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






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






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






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






24. Current flow in which electrons reverse direction at regular intervals.






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






26. 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.






27. A series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.






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






29. The act of breaking a particular subject into different parts to achieve clarity of understanding.






30. The amount of resistance the power system must overcome or - alternatively - the amount of force output by the power system: also can be referred to as weight or pressure.






31. 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.






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






33. The use of force to act on an object in order to move move the object in the same direction as the force.






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






35. The splitting of the nucleus of an atom.






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






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






38. Restriction or limit placed on a product.






39. The unlawful acquisition of some one's personal information for use without their consent.






40. A production system in which products are made one at a time according to customer's specifications.






41. The process of creating the most effective and functional product or process while meeting all the criteria and constraints.






42. A group of parts that work together to accomplish a goal. The basic parts of a system are input - process - and output.






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






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






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






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


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






48. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






49. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






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