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 capacity to do work or exert effort.






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






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






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






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






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






8. Restriction or limit placed on a product.






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






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






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






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






13. The capacity to do work or exert effort.






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






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






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






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






18. 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.






19. A method of obtaining energy from waste products






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






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






22. Energy in motion.






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






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






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






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






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






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






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






31. A resource that is entered into a system.






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






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






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






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






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






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






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






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






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






41. Someone who starts a business.






42. Stored energy or energy at rest.






43. 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.






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






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






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






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






48. 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.






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






50. The formal rules that guide the design process.
