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 computers in each stage of the design process.






2. 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.






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






4. A resource that is entered into a system.






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






6. The splitting of the nucleus of an atom.






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






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






9. Creating things through the process of planning.






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






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






12. Stored energy or energy at rest.






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






14. Energy in motion.






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






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






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






18. 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.






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






20. 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.






21. 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.






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






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






24. The formal rules that guide the design process.






25. The basic framework of a system






26. 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.






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






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






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






30. 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.'






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






32. The capacity to do work or exert effort.






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






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






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






36. 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.






37. A method of obtaining energy from waste products






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






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






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


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






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






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






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






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






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






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






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






49. 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.






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