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 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.






2. A method of obtaining energy from waste products






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






4. 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.






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






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






7. The capacity to do work or exert effort.






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






9. Restriction or limit placed on a product.






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






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






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






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






14. 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.






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






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






17. 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.






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






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






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






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






22. The formal rules that guide the design process.






23. 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.'






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






25. The capacity to do work or exert effort.






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






27. Creating things through the process of planning.






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






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






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






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






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


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






34. The basic framework of a system






35. Someone who starts a business.






36. 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.






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






38. 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.






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






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






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






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






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






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






45. Stored energy or energy at rest.






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






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






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






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






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