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 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.






2. The judgement of the end result based upon given criteria.






3. The capacity to do work or exert effort.






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






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






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






7. 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.






8. Someone who starts a business.






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






10. 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.






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






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






13. A popular movement.






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






15. 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.






16. 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.






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






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






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






20. A resource that is entered into a system.






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






22. 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.






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






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






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






26. 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.'






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






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


29. 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.






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






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






32. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






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






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






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






45. Energy in motion.






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






47. The basic framework of a system






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






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






50. A method of obtaining energy from waste products
