Technical Design And Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 30 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 use of lasers to record realistic images of three- dimensional objects.






2. 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.






3. The formal rules that guide the design process.






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






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






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






7. Someone who starts a business.






8. 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.






9. 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.






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






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






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






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 method of obtaining energy from waste products






15. 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.






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






17. 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.'






18. The basic framework of a system






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






20. 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.






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






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






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






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






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






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






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






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






29. A popular movement.






30. A resource that is entered into a system.






31. Stored energy or energy at rest.






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






33. The capacity to do work or exert effort.






34. 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.






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






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






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






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






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






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






41. 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.






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






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






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






45. Restriction or limit placed on a product.






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






47. The capacity to do work or exert effort.






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






49. The splitting of the nucleus of an atom.






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