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






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






3. A popular movement.






4. 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.'






5. 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.






6. 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.






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






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






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






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






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






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






13. The capacity to do work or exert effort.






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






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






16. A method of obtaining energy from waste products






17. The capacity to do work or exert effort.






18. The splitting of the nucleus of an atom.






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






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






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






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






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






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






25. 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.






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






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






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






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






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






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


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






33. 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.






34. 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.






35. A resource that is entered into a system.






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






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






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






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






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






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






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






43. The formal rules that guide the design process.






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






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






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






47. Stored energy or energy at rest.






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






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






50. 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.
