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






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






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






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






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






6. 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.






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






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






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






10. Energy in motion.






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






12. Stored energy or energy at rest.






13. The capacity to do work or exert effort.






14. Someone who starts a business.






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






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






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. Standards that a product must meet to be accepted.






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






20. Creating things through the process of planning.






21. 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.






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






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






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






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






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






29. The formal rules that guide the design process.






30. Restriction or limit placed on a product.






31. 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.






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






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






34. A method of obtaining energy from waste products






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


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






37. A popular movement.






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






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






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






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






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






43. 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.






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






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






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






47. The splitting of the nucleus of an atom.






48. The capacity to do work or exert effort.






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






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