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






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






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






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






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






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






7. A method of obtaining energy from waste products






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






9. The formal rules that guide the design process.






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






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






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






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






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






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






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






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






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






19. A resource that is entered into a system.






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






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






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






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






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






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






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






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






28. The capacity to do work or exert effort.






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






30. 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.






31. Energy in motion.






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






33. Someone who starts a business.






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






35. 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.






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






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






38. 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.






39. Stored energy or energy at rest.






40. 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.






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






42. 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.






43. A popular movement.






44. 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.






45. The basic framework of a system






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






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


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






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






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