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. Restriction or limit placed on a product.






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






3. 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.






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






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






6. The splitting of the nucleus of an atom.






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






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






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






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






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






12. 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.






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






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






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






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






17. 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.






18. 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.






19. The formal rules that guide the design process.






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






21. 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.






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






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






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






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






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






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






28. A popular movement.






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






30. The capacity to do work or exert effort.






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






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






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






34. Energy in motion.






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






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






37. The capacity to do work or exert effort.






38. 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.'






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






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






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






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






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






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






45. Someone who starts a business.






46. 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.






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






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






49. A method of obtaining energy from waste products






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