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 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.






2. The capacity to do work or exert effort.






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






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






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






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






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






8. Restriction or limit placed on a product.






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






10. A resource that is entered into a system.






11. 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.






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






13. The capacity to do work or exert effort.






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






17. 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.






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






19. 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.'






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






21. The formal rules that guide the design process.






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






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






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






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






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






27. A popular movement.






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






29. 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.






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






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






32. 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.






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






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






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






36. The basic framework of a system






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






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






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






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






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






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






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


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






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






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






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






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






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






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