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 superimposition of sine waves on electromagnetic carrier waves.






2. 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.






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






4. A resource that is entered into a system.






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






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






7. A popular movement.






8. Energy in motion.






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






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






11. 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.






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






13. The capacity to do work or exert effort.






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






15. 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.






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






17. Someone who starts a business.






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






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






20. Creating things through the process of planning.






21. The capacity to do work or exert effort.






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






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






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






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






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






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






28. 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.






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






30. A method of obtaining energy from waste products






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






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






33. 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.






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






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






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






37. Stored energy or energy at rest.






38. 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.'






39. 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.






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






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






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






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






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






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






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






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






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






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






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