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






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






3. A popular movement.






4. 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.






5. The basic framework of a system






6. 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.






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






8. 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.






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






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






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






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






13. A method of obtaining energy from waste products






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






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






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






17. 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.






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






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






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






21. Restriction or limit placed on a product.






22. A resource that is entered into a system.






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






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






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






26. The formal rules that guide the design process.






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


28. 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.'






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






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






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






32. Someone who starts a business.






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






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






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






36. Energy in motion.






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






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






39. The capacity to do work or exert effort.






40. 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.






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






42. 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.






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






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






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






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






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






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






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






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