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






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






4. 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.






5. 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.'






6. Energy in motion.






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






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






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






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






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






12. Stored energy or energy at rest.






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






14. 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.






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






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






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






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






19. Someone who starts a business.






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






21. Restriction or limit placed on a product.






22. 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.






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






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






25. The capacity to do work or exert effort.






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






27. 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.






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






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






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






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






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






33. Creating things through the process of planning.






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






35. The formal rules that guide the design process.






36. A resource that is entered into a system.






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






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






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






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






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






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






43. 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.






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






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






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






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






48. 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.






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






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