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






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






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






4. 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.






5. 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.






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






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






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






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






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






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






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






13. 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.'






14. Stored energy or energy at rest.






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






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






17. 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.






18. The basic framework of a system






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






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






21. 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.






22. The capacity to do work or exert effort.






23. The splitting of the nucleus of an atom.






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






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






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






27. Energy in motion.






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






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






30. 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.






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






32. A resource that is entered into a system.






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






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






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






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

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






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






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






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






42. Creating things through the process of planning.






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






44. The capacity to do work or exert effort.






45. A popular movement.






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






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






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






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






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