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 group of people working together to accomplish a common goal.






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






3. 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.






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






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






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






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






8. The basic framework of a system






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






10. 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.






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






12. 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.






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






14. 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.






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






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






17. A method of obtaining energy from waste products






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






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






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






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






22. 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.






23. The act of breaking a particular subject into different parts to achieve clarity of understanding.






24. Stored energy or energy at rest.






25. Restriction or limit placed on a product.






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






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






28. A resource that is entered into a system.






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






30. A popular movement.






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






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


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






34. The capacity to do work or exert effort.






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






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






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






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






39. The capacity to do work or exert effort.






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






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






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






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






44. Energy in motion.






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






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






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






48. 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.






49. Creating things through the process of planning.






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