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 superimposition of sine waves on electromagnetic carrier waves.






2. 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.






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






4. A popular movement.






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






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






7. 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.






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






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






10. 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.






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






12. 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.






13. 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.






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






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






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






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






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






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


20. The formal rules that guide the design process.






21. 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.






22. The use of 3D CAD drawings to create real models of a product within a sort of time.






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






24. Someone who starts a business.






25. The basic framework of a system






26. Restriction or limit placed on a product.






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






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






29. The technology field focused on sending messages and other in formation using different means.






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






31. Energy in motion.






32. 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.






33. Creating things through the process of planning.






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






35. A method of obtaining energy from waste products






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






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






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






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






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






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






44. The capacity to do work or exert effort.






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






46. 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.'






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






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






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






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