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 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.






2. A method of obtaining energy from waste products






3. 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.






4. A resource that is entered into a system.






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






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






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






8. The formal rules that guide the design process.






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






10. 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.






11. A production process in which the part or product moves down a line from one station to the next while parts are added.






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


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






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






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






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






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






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






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






20. The basic framework of a system






21. 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.






22. Restriction or limit placed on a product.






23. Someone who starts a business.






24. A popular movement.






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






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






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






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






29. The capacity to do work or exert effort.






30. Stored energy or energy at rest.






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






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






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






34. 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.






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






36. Energy in motion.






37. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






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






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






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






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






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






43. 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.






44. Creating things through the process of planning.






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






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






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






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






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






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