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 formal rules that guide the design process.






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






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






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






6. 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.






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






8. The capacity to do work or exert effort.






9. 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.






10. 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.






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






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






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






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


15. Restriction or limit placed on a product.






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






17. 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.






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






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






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






21. A method of obtaining energy from waste products






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






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






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






25. A resource that is entered into a system.






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






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






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






29. Creating things through the process of planning.






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






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






32. The splitting of the nucleus of an atom.






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






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






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






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






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






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






39. 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.






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






41. 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.






42. Energy in motion.






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






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






45. The capacity to do work or exert effort.






46. A popular movement.






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






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






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






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