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


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






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






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






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






6. Stored energy or energy at rest.






7. 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.






8. The capacity to do work or exert effort.






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






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






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






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






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






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






15. A method of obtaining energy from waste products






16. 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.






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






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






19. The splitting of the nucleus of an atom.






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






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






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






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






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






25. The basic framework of a system






26. 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.






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






28. 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.






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






30. Someone who starts a business.






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






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






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






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






35. The capacity to do work or exert effort.






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






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






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






39. The formal rules that guide the design process.






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






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






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






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






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






45. A resource that is entered into a system.






46. Creating things through the process of planning.






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






48. 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.






49. Restriction or limit placed on a product.






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