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






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






3. A method of obtaining energy from waste products






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






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






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






7. Energy in motion.






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






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






10. 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.






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






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






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






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






16. The splitting of the nucleus of an atom.






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






18. 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.






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






20. The formal rules that guide the design process.






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






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






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






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






25. 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.






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






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






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






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






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






31. 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.






32. 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.






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


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






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






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






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






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






39. 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.






40. Someone who starts a business.






41. The capacity to do work or exert effort.






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






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






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






45. 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.






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






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






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






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






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