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






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






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






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






5. 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.






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






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






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






9. 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.






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






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






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






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






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






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






16. The splitting of the nucleus of an atom.






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






18. The capacity to do work or exert effort.






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






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






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






22. 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.






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






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






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






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






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


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






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






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






31. 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.






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






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






34. A popular movement.






35. Creating things through the process of planning.






36. The basic framework of a system






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






38. 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.






39. Energy in motion.






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






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






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






43. Someone who starts a business.






44. 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.






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






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






47. A method of obtaining energy from waste products






48. 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.






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






50. The formal rules that guide the design process.
