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






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






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






4. 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.






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






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






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






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






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






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






11. The splitting of the nucleus of an atom.






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






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






14. Creating things through the process of planning.






15. 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.






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






17. Stored energy or energy at rest.






18. 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.






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






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






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






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






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






24. The capacity to do work or exert effort.






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






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






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






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






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


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






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






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






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






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






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






37. 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.'






38. 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.






39. Someone who starts a business.






40. 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.






41. A resource that is entered into a system.






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






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






44. The capacity to do work or exert effort.






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






46. A popular movement.






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






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






49. 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.






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