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. Stored energy or energy at rest.






2. 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.






3. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






12. 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.






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






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






17. The capacity to do work or exert effort.






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






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






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






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






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






23. A resource that is entered into a system.






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






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






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






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






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






29. 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.






30. A method of obtaining energy from waste products






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






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






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






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






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






36. 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.






37. Energy in motion.






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






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






40. The splitting of the nucleus of an atom.






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






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


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






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






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






47. 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.






48. 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.






49. Someone who starts a business.






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