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 popular movement.






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






3. A resource that is entered into a system.






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






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






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






8. 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.






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. The capacity to do work or exert effort.






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






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






13. The capacity to do work or exert effort.






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






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






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






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






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






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


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






21. 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.






22. 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.






23. The splitting of the nucleus of an atom.






24. 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.






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






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






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






28. 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.






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






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






31. The basic framework of a system






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






33. Restriction or limit placed on a product.






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






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






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






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






38. The formal rules that guide the design process.






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






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






41. 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.'






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






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






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






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






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






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






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






49. 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.






50. A method of obtaining energy from waste products
