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






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






3. 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.






4. 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.






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






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






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






8. Stored energy or energy at rest.






9. The capacity to do work or exert effort.






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






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






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






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






14. The basic framework of a system






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






16. 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.'






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






18. 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.






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


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






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 force to act on an object in order to move move the object in the same direction as the force.






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






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






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






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






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






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






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






30. 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.






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






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






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






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






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






36. A popular movement.






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






38. The capacity to do work or exert effort.






39. A method of obtaining energy from waste products






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






41. 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.






42. 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.






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






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






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






46. Restriction or limit placed on a product.






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






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






49. Someone who starts a business.






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