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






2. 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.






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






4. A resource that is entered into a system.






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






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






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






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






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






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






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






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






13. The basic framework of a system






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






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






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






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






18. 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.






19. Someone who starts a business.






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






21. Energy in motion.






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






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






24. Creating things through the process of planning.






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


26. A method of obtaining energy from waste products






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






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






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






30. The formal rules that guide the design process.






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






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






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






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






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






36. The splitting of the nucleus of an atom.






37. The capacity to do work or exert effort.






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






39. 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.






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






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






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






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






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






45. 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.






46. Restriction or limit placed on a product.






47. Stored energy or energy at rest.






48. 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.






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






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.
