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






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






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






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






5. A popular movement.






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






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






8. Energy in motion.






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






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






11. 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.






12. 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.






13. 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.'






14. 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.






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






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


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






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






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






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






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






22. Restriction or limit placed on a product.






23. 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.






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






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






26. 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.






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






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






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






30. 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.






31. A resource that is entered into a system.






32. A method of obtaining energy from waste products






33. 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.






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






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






36. Someone who starts a business.






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






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






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






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






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






42. Creating things through the process of planning.






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






44. The basic framework of a system






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






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






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






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






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






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