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






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






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






5. The basic framework of a system






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






7. Energy in motion.






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






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






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






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






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






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






14. The capacity to do work or exert effort.






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






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






17. 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.






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






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






20. Stored energy or energy at rest.






21. A method of obtaining energy from waste products






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






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






24. 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.






25. 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.






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






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






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






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






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






31. 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.






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






33. The capacity to do work or exert effort.






34. 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.






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






36. Someone who starts a business.






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






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






39. The splitting of the nucleus of an atom.






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






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






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






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






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






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






46. 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.






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






48. Creating things through the process of planning.






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






50. The formal rules that guide the design process.
