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






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






3. The capacity to do work or exert effort.






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






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






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






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






8. Creating things through the process of planning.






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






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






11. 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.






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






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






14. 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.'






15. 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.






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






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






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






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






20. 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.






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






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


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






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






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






26. A method of obtaining energy from waste products






27. Stored energy or energy at rest.






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






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






30. The basic framework of a system






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






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






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






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






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






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






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






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






41. The capacity to do work or exert effort.






42. The splitting of the nucleus of an atom.






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






44. A popular movement.






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






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






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






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






49. Restriction or limit placed on a product.






50. 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.
