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 lasers to record realistic images of three- dimensional objects.






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






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






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






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






6. 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.






7. Energy in motion.






8. Someone who starts a business.






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






10. 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.






11. Restriction or limit placed on a product.






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






13. The use of 3D CAD drawings to create real models of a product within a sort of time.






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






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






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






17. A popular movement.






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






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






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






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






22. 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.'






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






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






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






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






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






28. A method of obtaining energy from waste products






29. 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.






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






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






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






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






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






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






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






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






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






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






40. The capacity to do work or exert effort.






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






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






43. The formal rules that guide the design process.






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






45. 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.






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






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






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






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






50. 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.
