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






2. Creating things through the process of planning.






3. 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.






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






5. 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.






6. 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.






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






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






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






10. Stored energy or energy at rest.






11. 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.'






12. The capacity to do work or exert effort.






13. The formal rules that guide the design process.






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






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






16. 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.






17. A popular movement.






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






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






20. 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.






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






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






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






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






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






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






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






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






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






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






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






32. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






33. 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.






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






35. Restriction or limit placed on a product.






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






37. A resource that is entered into a system.






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






39. The splitting of the nucleus of an atom.






40. The basic framework of a system






41. 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.






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






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






44. 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.






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






46. Energy in motion.






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






48. A method of obtaining energy from waste products






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






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