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






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






3. 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.






4. Someone who starts a business.






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






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






7. Creating things through the process of planning.






8. 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.






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






10. 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.'






11. 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.






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






13. A resource that is entered into a system.






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






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






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






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






18. Restriction or limit placed on a product.






19. A method of obtaining energy from waste products






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






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






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






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






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






25. The basic framework of a system






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


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






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






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






30. 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.






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






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






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






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






35. Stored energy or energy at rest.






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






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






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






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






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






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






42. 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.






43. 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.






44. 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.






45. The splitting of the nucleus of an atom.






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






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






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






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






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