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






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






3. 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.






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






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






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






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






8. 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.






9. The capacity to do work or exert effort.






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






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






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






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






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






15. The splitting of the nucleus of an atom.






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






17. Energy in motion.






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






19. Stored energy or energy at rest.






20. Someone who starts a business.






21. 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.






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






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






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






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






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






27. Creating things through the process of planning.






28. 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.






29. 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.






30. 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.






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






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






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






34. The formal rules that guide the design process.






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






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






37. 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.'






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






39. A popular movement.






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






41. A resource that is entered into a system.






42. Restriction or limit placed on a product.






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






44. The basic framework of a system






45. A device capable of detecting (sensing) changes in its environment; light and movement are examples.






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






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






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






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