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






2. The splitting of the nucleus of an atom.






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






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






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






7. 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.






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






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






10. Someone who starts a business.






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






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






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


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






15. The basic framework of a system






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






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






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






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






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






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






24. The capacity to do work or exert effort.






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. A popular movement.






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






28. A resource that is entered into a system.






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






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






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






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






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






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






35. The formal rules that guide the design process.






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






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






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






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






40. 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.






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






42. 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.






43. Creating things through the process of planning.






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






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






46. A method of obtaining energy from waste products






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






48. Stored energy or energy at rest.






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






50. 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.
