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






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






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


4. 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.






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






6. Someone who starts a business.






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






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






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






10. The capacity to do work or exert effort.






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






12. 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.






13. The formal rules that guide the design process.






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






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






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






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






18. 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.'






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






20. A resource that is entered into a system.






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






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






23. 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.






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






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






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






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






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






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






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






31. Energy in motion.






32. The capacity to do work or exert effort.






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






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






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






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






37. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






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






39. Stored energy or energy at rest.






40. The splitting of the nucleus of an atom.






41. The basic framework of a system






42. 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.






43. 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.






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






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






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






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






48. Restriction or limit placed on a product.






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






50. Creating things through the process of planning.
