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






2. Stored energy or energy at rest.






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






4. 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.






5. The capacity to do work or exert effort.






6. The formal rules that guide the design process.






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






8. The use of force to act on an object in order to move move the object in the same direction as the force.






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






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






11. The capacity to do work or exert effort.






12. 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.






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






14. 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.






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






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






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






18. 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.






19. 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.






20. 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.






21. 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.






22. Someone who starts a business.






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






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






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






26. The splitting of the nucleus of an atom.






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






28. 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.






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






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


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






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






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






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






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






36. 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.






37. The basic framework of a system






38. A resource that is entered into a system.






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






40. A popular movement.






41. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






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