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






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






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






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






6. Energy in motion.






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






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






9. Creating things through the process of planning.






10. Someone who starts a business.






11. 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.






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






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






14. A method of obtaining energy from waste products






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






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






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






18. A resource that is entered into a system.






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






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






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






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






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


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






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






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






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






28. 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.






29. The basic framework of a system






30. 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.






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






32. 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.






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






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






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






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






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






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






39. 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.






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






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






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






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






44. The formal rules that guide the design process.






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






46. 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.'






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






48. 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.






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






50. Restriction or limit placed on a product.
