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. 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.






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






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






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






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


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






7. A popular movement.






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






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






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






12. 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.






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






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






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






16. The splitting of the nucleus of an atom.






17. Stored energy or energy at rest.






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






19. 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.






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






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






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






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






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






25. Someone who starts a business.






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






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






28. The formal rules that guide the design process.






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






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






31. 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.






32. A resource that is entered into a system.






33. 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.'






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






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






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






37. 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.






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






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






40. 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.






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






42. Restriction or limit placed on a product.






43. Energy in motion.






44. A method of obtaining energy from waste products






45. The capacity to do work or exert effort.






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






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






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






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






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