Test your basic knowledge |

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 group of people working together to accomplish a common goal.






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






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






4. 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.






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






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






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






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






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






10. A popular movement.






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






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






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






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






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






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






17. The formal rules that guide the design process.






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






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






20. A resource that is entered into a system.






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






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






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






25. Creating things through the process of planning.






26. The splitting of the nucleus of an atom.






27. 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.






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






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






30. 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.'






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






32. Stored energy or energy at rest.






33. The capacity to do work or exert effort.






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






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






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






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






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






39. 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.






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






41. Energy in motion.






42. 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.






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






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






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






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






47. 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.






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






49. 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.






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