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 superimposition of sine waves on electromagnetic carrier waves.






2. 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.






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






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






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






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






7. 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.






8. A method of obtaining energy from waste products






9. The formal rules that guide the design process.






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






11. Stored energy or energy at rest.






12. 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.






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






14. 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.






15. Someone who starts a business.






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






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






18. The basic framework of a system






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






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






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






22. Creating things through the process of planning.






23. The capacity to do work or exert effort.






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






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






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






27. 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.'






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






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






30. The splitting of the nucleus of an atom.






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






32. 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.






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






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


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






36. Restriction or limit placed on a product.






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






38. A resource that is entered into a system.






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






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






41. 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.






42. 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.






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






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






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






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






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






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






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






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