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 method of obtaining energy from waste products






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






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






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






5. 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.






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






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






8. 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.






9. 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.






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






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






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






13. Restriction or limit placed on a product.






14. 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.'






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






16. 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.






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






18. Someone who starts a business.






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. Stored energy or energy at rest.






21. The capacity to do work or exert effort.






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






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






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






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






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






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






28. A resource that is entered into a system.






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






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






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






32. 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.






33. The splitting of the nucleus of an atom.






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






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






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






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






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






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


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






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






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






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






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






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






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






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






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






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