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






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






3. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






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






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






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. The capacity to do work or exert effort.






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






17. The basic framework of a system






18. 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.






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






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






21. The formal rules that guide the design process.






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






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






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






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


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






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






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






29. A popular movement.






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






31. Restriction or limit placed on a product.






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






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






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






35. 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.






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






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






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






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






40. 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.






41. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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