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






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






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. 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.






5. 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.'






6. 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.






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

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






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






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






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






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






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






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






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






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






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






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






19. The splitting of the nucleus of an atom.






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






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






22. 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.






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






24. Creating things through the process of planning.






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






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






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






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






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






30. A popular movement.






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






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






33. A method of obtaining energy from waste products






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






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






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






37. Someone who starts a business.






38. 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.






39. 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.






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






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






42. The use of 3D CAD drawings to create real models of a product within a sort of time.






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






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






45. 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.






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






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






48. A resource that is entered into a system.






49. The basic framework of a system






50. The formal rules that guide the design process.
