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






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


3. The act of putting different things together to form a new product or idea.






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






5. A resource that is entered into a system.






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






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






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






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






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






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






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






13. The splitting of the nucleus of an atom.






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






15. 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.






16. 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.






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






18. 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.






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






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






21. 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.






22. 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.






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






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






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






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






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






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






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






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






31. 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.






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






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






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






35. Stored energy or energy at rest.






36. The capacity to do work or exert effort.






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






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






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






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






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






43. A popular movement.






44. Energy in motion.






45. Restriction or limit placed on a product.






46. 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.






47. 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.






48. The basic framework of a system






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






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