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 money a business makes after all expenses have been paid






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






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






4. 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.






5. Someone who starts a business.






6. Creating things through the process of planning.






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






8. Restriction or limit placed on a product.






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






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






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






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






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






14. The formal rules that guide the design process.






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






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






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






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






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






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






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


22. 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.






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






24. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






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






26. A resource that is entered into a system.






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






28. 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.






29. Stored energy or energy at rest.






30. The capacity to do work or exert effort.






31. 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.






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






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






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






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






36. The splitting of the nucleus of an atom.






37. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






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






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






48. 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.






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






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