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






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






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






4. 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.






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






6. 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.






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






8. The formal rules that guide the design process.






9. A method of obtaining energy from waste products






10. The capacity to do work or exert effort.






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






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






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






14. The splitting of the nucleus of an atom.






15. 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.






16. A popular movement.






17. A resource that is entered into a system.






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






19. 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.






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






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






22. Stored energy or energy at rest.






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






24. 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.






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






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






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






28. The capacity to do work or exert effort.






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






30. Energy in motion.






31. 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.






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






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






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






35. The basic framework of a system






36. Restriction or limit placed on a product.






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






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






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






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






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






42. 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.






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






44. 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.'






45. 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.






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






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






48. Someone who starts a business.






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






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