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






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






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






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






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






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






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






9. 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.






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






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






12. The formal rules that guide the design process.






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






14. 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.






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






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






17. The basic framework of a system






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






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






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






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






23. 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.






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






25. A method of obtaining energy from waste products






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






27. 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.'






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






29. 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.






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






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






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


33. 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.






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






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. Creating things through the process of planning.






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






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






39. 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.






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






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






42. A popular movement.






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






44. The capacity to do work or exert effort.






45. Energy in motion.






46. Someone who starts a business.






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






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






49. Stored energy or energy at rest.






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.
