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. A method of obtaining energy from waste products






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






3. The basic framework of a system






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






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


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






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






8. 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.






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






10. 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.






11. 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.






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






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






14. 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.






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






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






17. The capacity to do work or exert effort.






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






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






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. Someone who starts a business.






22. A popular movement.






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






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






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






26. The capacity to do work or exert effort.






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






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






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






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






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






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






33. A resource that is entered into a system.






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






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






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






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






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






39. The formal rules that guide the design process.






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






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






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






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






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






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






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






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






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






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






50. The splitting of the nucleus of an atom.
