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






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






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






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






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






6. 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.






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






8. 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.






9. 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.






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






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






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






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






14. The capacity to do work or exert effort.






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






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






17. Energy in motion.






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






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






20. The capacity to do work or exert effort.






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






22. 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.






23. The splitting of the nucleus of an atom.






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






25. Someone who starts a business.






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






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






28. A method of obtaining energy from waste products






29. 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.






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






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






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






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






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






35. 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.






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






37. 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.






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






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






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






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






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






43. 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.






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






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






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






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






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






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






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