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 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.






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






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






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






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






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






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






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






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






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






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






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






13. The splitting of the nucleus of an atom.






14. Creating things through the process of planning.






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






16. 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.






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






18. 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.






19. A resource that is entered into a system.






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






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






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






23. The capacity to do work or exert effort.






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






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






26. A popular movement.






27. 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.






28. 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.






29. Energy in motion.






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






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






32. Restriction or limit placed on a product.






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






34. 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.






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






36. 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.






37. The basic framework of a system






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






39. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






48. Someone who starts a business.






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






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