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 pressurized liquid or gasses to control and transmit power.






2. Energy in motion.






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






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






5. 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.'






6. Restriction or limit placed on a product.






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






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






9. 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.






10. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






11. 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.






12. The basic framework of a system






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






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






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






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






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






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






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






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






21. 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.






22. The capacity to do work or exert effort.






23. 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.






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






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






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






27. 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.






28. 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.






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






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






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






32. Stored energy or energy at rest.






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






34. A popular movement.






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






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






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






38. The long term storage mechanism of a computer. It holds the computer programs used for word processing - playing games - and other tasks.






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






40. A resource that is entered into a system.






41. Someone who starts a business.






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






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






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






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






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






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






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






49. The capacity to do work or exert effort.






50. 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.
