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 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.






2. Stored energy or energy at rest.






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






4. The capacity to do work or exert effort.






5. The capacity to do work or exert effort.






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






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






8. 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.






9. Creating things through the process of planning.






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






11. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






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






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






14. 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.






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






16. 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.






17. A popular movement.






18. 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.






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






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






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






22. The basic framework of a system






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






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






25. 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.






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


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






28. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






45. Energy in motion.






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






47. Restriction or limit placed on a product.






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






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






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