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. Stored energy or energy at rest.






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






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






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






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






6. Someone who starts a business.






7. The formal rules that guide the design process.






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






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






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






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






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






13. 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.






14. The capacity to do work or exert effort.






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






16. The basic framework of a system






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






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






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






20. Creating things through the process of planning.






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






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






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






24. 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.






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






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






27. Energy in motion.






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






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






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






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






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






34. 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.






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






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






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






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






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






40. 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.






41. 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.






42. Restriction or limit placed on a product.






43. 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.






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






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






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






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






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






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






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.
