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






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






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






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






5. Creating things through the process of planning.






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






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






8. 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.






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






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






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






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






13. 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.






14. 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.






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






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






17. Stored energy or energy at rest.






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






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






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






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






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






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






24. 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.






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






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






27. A popular movement.






28. The splitting of the nucleus of an atom.






29. 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.'






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






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






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






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






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






35. Someone who starts a business.






36. The formal rules that guide the design process.






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






38. A method of obtaining energy from waste products






39. Energy in motion.






40. 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.






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






42. Restriction or limit placed on a product.






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






44. The capacity to do work or exert effort.






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






46. 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.






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


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






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






50. 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.
