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






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






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






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






6. A resource that is entered into a system.






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






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






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






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






11. The capacity to do work or exert effort.






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






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






14. The basic framework of a system






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






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






17. Restriction or limit placed on a product.






18. 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.






19. A popular movement.






20. Stored energy or energy at rest.






21. Someone who starts a business.






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






23. 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.'






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






25. The formal rules that guide the design process.






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






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






28. 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.






29. 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.






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


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






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






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






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






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






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






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






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






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






40. Creating things through the process of planning.






41. The splitting of the nucleus of an atom.






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






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






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






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






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






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






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






50. 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.
