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 path by which electric current or pulses flow.






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






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






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






5. 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.






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






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


9. 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.






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






11. 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.






12. A resource that is entered into a system.






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






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






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






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






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






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






20. Creating things through the process of planning.






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






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






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






24. The splitting of the nucleus of an atom.






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






26. A popular movement.






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






28. The formal rules that guide the design process.






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






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






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






32. A method of obtaining energy from waste products






33. 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.






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






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






36. Restriction or limit placed on a product.






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






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






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






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






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






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






43. The capacity to do work or exert effort.






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






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






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






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






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






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






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