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






2. The capacity to do work or exert effort.






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






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






5. 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.






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






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






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






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






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






11. The basic framework of a system






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






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






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






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






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






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






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






19. The splitting of the nucleus of an atom.






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






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






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






23. Restriction or limit placed on a product.






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






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






26. 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.'






27. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






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


29. 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.






30. Someone who starts a business.






31. 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.






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






33. 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.






34. The formal rules that guide the design process.






35. Creating things through the process of planning.






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






37. 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.






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






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






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






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






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






43. A resource that is entered into a system.






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






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






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






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






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






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






50. The capacity to do work or exert effort.
