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 capacity to do work or exert effort.






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






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






4. Energy in motion.






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






6. 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.






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






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






9. 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.






10. Someone who starts a business.






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






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






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






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






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






16. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






17. 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.






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






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






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






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






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






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


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






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






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






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






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






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. A resource that is entered into a system.






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






32. Creating things through the process of planning.






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






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






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






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






37. The basic framework of a system






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






39. 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.






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






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






42. In a computer - the primary circuit board to which all internal componnets are connected either directly or indirectly.






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






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






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






46. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






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






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






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






50. A method of obtaining energy from waste products
