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 a computer system to produce technical drawings and/or design a product.






2. A resource that is entered into a system.






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






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






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






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






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






8. The act of putting different things together to form a new product or idea.






9. 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.'






10. 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.






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






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






13. The splitting of the nucleus of an atom.






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






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






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






17. The formal rules that guide the design process.






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






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






20. 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.






21. 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.






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






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






24. A popular movement.






25. 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.






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






27. Energy in motion.






28. The capacity to do work or exert effort.






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






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






31. 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.






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






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






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






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






36. 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.






37. 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.






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






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






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






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






42. The capacity to do work or exert effort.






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






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






45. 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.






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






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






48. Restriction or limit placed on a product.






49. A method of obtaining energy from waste products






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