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 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.






2. Someone who starts a business.






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






4. Stored energy or energy at rest.






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






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






7. 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.






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


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






10. A resource that is entered into a system.






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






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






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






14. Energy in motion.






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






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






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






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






19. 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.






20. The formal rules that guide the design process.






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






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






23. 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.






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






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






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






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






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






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






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






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






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






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






35. 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.






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






37. A method of obtaining energy from waste products






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






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






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






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






42. A popular movement.






43. 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.






44. The basic framework of a system






45. The capacity to do work or exert effort.






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






47. Creating things through the process of planning.






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






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