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






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






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






5. The splitting of the nucleus of an atom.






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






7. 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.






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






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






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






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






12. The capacity to do work or exert effort.






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






14. Someone who starts a business.






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






16. The formal rules that guide the design process.






17. 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.






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






19. 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.'






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






21. Creating things through the process of planning.






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






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






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






25. 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.






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






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






28. The capacity to do work or exert effort.






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






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






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






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






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






34. 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.






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






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






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






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






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






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






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






42. Restriction or limit placed on a product.






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






44. 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.






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






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






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






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






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






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