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






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






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






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






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






7. 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.






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






9. The capacity to do work or exert effort.






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






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






12. 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.






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






14. Energy in motion.






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






16. The splitting of the nucleus of an atom.






17. A popular movement.






18. Restriction or limit placed on a product.






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






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






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






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






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






24. Someone who starts a business.






25. 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.






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






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






28. Creating things through the process of planning.






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






30. 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.






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






32. A method of obtaining energy from waste products






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






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






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






36. 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.'






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






38. 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.






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






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






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






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






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






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






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






46. 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.






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






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






49. 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.






50. A series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.
