Test your basic knowledge |

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






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






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






5. The capacity to do work or exert effort.






6. A popular movement.






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






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






9. 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.






10. The capacity to do work or exert effort.






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






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






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






14. 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.






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






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






17. Restriction or limit placed on a product.






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


19. Creating things through the process of planning.






20. 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.






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






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






24. A resource that is entered into a system.






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






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






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






28. 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.






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






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






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






32. 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.






33. 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.






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






35. The basic framework of a system






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






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






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






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






40. 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.






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






42. Stored energy or energy at rest.






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






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






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






46. The splitting of the nucleus of an atom.






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






48. Someone who starts a business.






49. A method of obtaining energy from waste products






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