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






2. The formal rules that guide the design process.






3. 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.






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






5. 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.






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






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






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






9. Energy in motion.






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






11. 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.






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






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






14. Stored energy or energy at rest.






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






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






17. 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.






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






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






20. A production process in which the part or product moves down a line from one station to the next while parts are added.






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






22. 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.






23. 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.'






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






25. 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.






26. 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.






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






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






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


30. The capacity to do work or exert effort.






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






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






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






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






35. The basic framework of a system






36. A popular movement.






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






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






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






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






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






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






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






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






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






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






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






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






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