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






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






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






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






5. Restriction or limit placed on a product.






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






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






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






9. 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.






10. Energy in motion.






11. The splitting of the nucleus of an atom.






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






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






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






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






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






17. 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.






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






19. 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.






20. Someone who starts a business.






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






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






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






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






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






26. The formal rules that guide the design process.






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






28. 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.






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






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






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






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






33. A method of obtaining energy from waste products






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






35. 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.






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






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






38. 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.'






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






41. The capacity to do work or exert effort.






42. Creating things through the process of planning.






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






44. Stored energy or energy at rest.






45. The capacity to do work or exert effort.






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






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






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






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






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