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






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






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 judgement of the end result based upon given criteria.






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






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






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






9. The splitting of the nucleus of an atom.






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






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. 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 basic framework of a system






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






15. 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.






16. Energy in motion.






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






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






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






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






21. A language - used to write computer programs - that can easily be translated into machine language.






22. A method of obtaining energy from waste products






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


24. Stored energy or energy at rest.






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






26. Restriction or limit placed on a product.






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






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






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






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






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






32. Someone who starts a business.






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






34. 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.






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






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






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






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






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






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






41. 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.






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






43. Creating things through the process of planning.






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






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






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






47. The capacity to do work or exert effort.






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






49. 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.






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