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






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






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






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






6. Restriction or limit placed on a product.






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






8. A popular movement.






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






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






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






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






13. Creating things through the process of planning.






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






15. 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.






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






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






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






19. Energy in motion.






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






21. 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.






22. 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.






23. Someone who starts a business.






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






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






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






27. The splitting of the nucleus of an atom.






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






29. The capacity to do work or exert effort.






30. 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.






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






32. The basic framework of a system






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






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






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






36. The formal rules that guide the design process.






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






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






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


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






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






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






43. 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.






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






45. A resource that is entered into a system.






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






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






48. Stored energy or energy at rest.






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






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