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 path by which electric current or pulses flow.






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






3. 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.






4. 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.'






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






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






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






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






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






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


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






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






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






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






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






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






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






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






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






20. The capacity to do work or exert effort.






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






22. Creating things through the process of planning.






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






24. Energy in motion.






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






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






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






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






29. Stored energy or energy at rest.






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






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






32. The splitting of the nucleus of an atom.






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






34. 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.






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






36. 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.






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






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






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






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






41. 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.






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






43. A popular movement.






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






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






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






47. The basic framework of a system






48. 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.






49. 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.






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