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. Restriction or limit placed on a product.






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






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






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






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






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






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






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






9. 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.






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






11. The splitting of the nucleus of an atom.






12. 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.






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






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






15. Energy in motion.






16. A resource that is entered into a system.






17. 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.'






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






19. 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.






20. A method of obtaining energy from waste products






21. Stored energy or energy at rest.






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






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






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






25. 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.






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






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






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






29. The capacity to do work or exert effort.






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






31. A device that orbits the Earth and receives messages from one location and transmits them to another.






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






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






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






35. 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.






36. The process of turning abstractions of thought into concrete ideas.






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






38. Creating things through the process of planning.






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






40. The formal rules that guide the design process.






41. Someone who starts a business.






42. 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.






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






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






45. 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.






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






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






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


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






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