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






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






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






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






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






7. Someone who starts a business.






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






9. 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.






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






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






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






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






14. 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.






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






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






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






18. 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.






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






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






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






22. The splitting of the nucleus of an atom.






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






24. 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.






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






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






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






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






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






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






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






32. Energy in motion.






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






34. Restriction or limit placed on a product.






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






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






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






38. The capacity to do work or exert effort.






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






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






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






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






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






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






45. A popular movement.






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






47. 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.






48. The formal rules that guide the design process.






49. 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.






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