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 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.'






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






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






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






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






6. 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.






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






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






9. 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.






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






11. A popular movement.






12. 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.






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






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


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






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






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






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






19. Someone who starts a business.






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






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






22. Creating things through the process of planning.






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






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






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






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






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






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






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






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






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






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






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






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






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






36. The capacity to do work or exert effort.






37. Energy in motion.






38. Restriction or limit placed on a product.






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






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






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






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






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






44. 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.






45. A method of obtaining energy from waste products






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






47. The formal rules that guide the design process.






48. 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.






49. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






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