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






2. A method of obtaining energy from waste products






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






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






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






6. 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.






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






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






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






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






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






12. 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.






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






14. Creating things through the process of planning.






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






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






17. Restriction or limit placed on a product.






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. Someone who starts a business.






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






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






22. The capacity to do work or exert effort.






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






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






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






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






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






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






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






30. Stored energy or energy at rest.






31. 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.






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






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






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






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






36. 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.






37. A resource that is entered into a system.






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






39. A popular movement.






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






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






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






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






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






45. The formal rules that guide the design process.






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






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






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






49. The capacity to do work or exert effort.






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