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






2. The basic framework of a system






3. A method of obtaining energy from waste products






4. A popular movement.






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






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






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






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






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






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






11. 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.






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






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






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






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 capacity to do work or exert effort.






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






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






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






22. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






23. The unlawful acquisition of some one's personal information for use without their consent.






24. Energy in motion.






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






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






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






28. 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.






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






30. A resource that is entered into a system.






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






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






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






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






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






36. The formal rules that guide the design process.






37. 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.'






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






39. Someone who starts a business.






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. 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.






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






44. The splitting of the nucleus of an atom.






45. Creating things through the process of planning.






46. The capacity to do work or exert effort.






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






48. 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.






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






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