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






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


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






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






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






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






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






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






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






10. 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.






11. The formal rules that guide the design process.






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






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






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






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






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






17. 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.'






18. 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.






19. 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.






20. The capacity to do work or exert effort.






21. 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.






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






23. A popular movement.






24. A method of obtaining energy from waste products






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






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






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






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






29. 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.






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






31. Creating things through the process of planning.






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






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






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






35. Restriction or limit placed on a product.






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






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






38. Stored energy or energy at rest.






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






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






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






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






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






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






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






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






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






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






49. The basic framework of a system






50. 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.
