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






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






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






5. A popular movement.






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






7. A resource that is entered into a system.






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






9. The capacity to do work or exert effort.






10. 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.






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






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






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






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






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






16. 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.






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






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






19. Energy in motion.






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






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


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






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






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






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






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






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






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






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






30. Restriction or limit placed on a product.






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






32. The formal rules that guide the design process.






33. The basic framework of a system






34. 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.






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






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






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






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






39. The splitting of the nucleus of an atom.






40. 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.






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






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






43. Someone who starts a business.






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






45. The capacity to do work or exert effort.






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






47. 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.






48. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






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






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