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






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






3. 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.






4. A resource that is entered into a system.






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






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






7. The capacity to do work or exert effort.






8. Creating things through the process of planning.






9. 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.






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






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






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






13. The splitting of the nucleus of an atom.






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






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






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






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






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






19. 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.






20. A method of obtaining energy from waste products






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






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






23. 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.






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






25. The basic framework of a system






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






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






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






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






30. The formal rules that guide the design process.






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






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






33. 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.






34. Restriction or limit placed on a product.






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






36. 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.'






37. Energy in motion.






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






41. 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.






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






43. 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.






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






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






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






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






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






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






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