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






2. The capacity to do work or exert effort.






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






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






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






6. Restriction or limit placed on a product.






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






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






9. Someone who starts a business.






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






11. The basic framework of a system






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






13. Energy in motion.






14. 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.






15. Creating things through the process of planning.






16. 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.'






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






18. 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.






19. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






29. The formal rules that guide the design process.






30. 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.






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






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






33. 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.






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






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






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






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


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






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






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






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






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






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






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






45. 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.






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






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






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






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






50. 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.
