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






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






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






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

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






6. 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.






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






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






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






10. The basic framework of a system






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






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






13. 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.






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






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






16. 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.






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






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






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






20. 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.






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






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






23. Energy in motion.






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






25. The formal rules that guide the design process.






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






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






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






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






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






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






32. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






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






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






35. 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.






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






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






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






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






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






41. Creating things through the process of planning.






42. Restriction or limit placed on a product.






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






44. 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.'






45. The capacity to do work or exert effort.






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






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






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






49. A method of obtaining energy from waste products






50. 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.
