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






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






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






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






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






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






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






8. 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.






9. The splitting of the nucleus of an atom.






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






11. The capacity to do work or exert effort.






12. 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.






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






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






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






16. 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.






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






18. The basic framework of a system






19. The capacity to do work or exert effort.






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






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






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






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






24. 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.'






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






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






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






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






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






30. A method of obtaining energy from waste products






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






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






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






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






35. A popular movement.






36. 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.






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






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


39. 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.






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






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






42. Creating things through the process of planning.






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






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






45. 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.






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






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






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






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






50. Restriction or limit placed on a product.
