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. Someone who starts a business.






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






3. A popular movement.






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






5. 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.






6. 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.






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






8. Energy in motion.






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 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.






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






12. 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.






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






14. The basic framework of a system






15. Stored energy or energy at rest.






16. 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.






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






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






19. 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.






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






21. The capacity to do work or exert effort.






22. Creating things through the process of planning.






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






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






25. 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.'






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






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






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






29. The splitting of the nucleus of an atom.






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






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






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






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






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






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






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






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






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






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






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






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






42. A method of obtaining energy from waste products






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






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






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






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






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






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






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






50. The formal rules that guide the design process.
