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






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






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






4. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






19. Energy in motion.






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






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






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






23. The splitting of the nucleus of an atom.






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






25. 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.






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






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






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






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






31. The formal rules that guide the design process.






32. Restriction or limit placed on a product.






33. 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.






34. 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.'






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






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


37. A popular movement.






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






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






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






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






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






43. A resource that is entered into a system.






44. The capacity to do work or exert effort.






45. 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.






46. Stored energy or energy at rest.






47. 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.






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






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






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