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. Creating things through the process of planning.






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






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






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






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. The capacity to do work or exert effort.






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






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






9. 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.






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






11. 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.






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






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






14. The formal rules that guide the design process.






15. 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.






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






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






18. Stored energy or energy at rest.






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






20. 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.






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






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






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






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






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






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






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






28. Energy in motion.






29. 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.






30. A popular movement.






31. The basic framework of a system






32. The splitting of the nucleus of an atom.






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






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






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






36. A resource that is entered into a system.






37. Someone who starts a business.






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

39. 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.






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






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






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






44. The capacity to do work or exert effort.






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






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






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






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






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






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