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






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






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






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






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






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






7. 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.'






8. Creating things through the process of planning.






9. The formal rules that guide the design process.






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






11. The capacity to do work or exert effort.






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






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






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






15. A resource that is entered into a system.






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






17. 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.






18. A method of obtaining energy from waste products






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






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






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






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






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






24. 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.






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






26. 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.






27. 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.






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






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






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






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






32. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






46. The splitting of the nucleus of an atom.






47. Energy in motion.






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






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 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.
