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 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.






2. Someone who starts a business.






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


4. A popular movement.






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






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






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






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






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






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






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






12. The formal rules that guide the design process.






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






14. Creating things through the process of planning.






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






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






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






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






19. A method of obtaining energy from waste products






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






21. The capacity to do work or exert effort.






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






23. 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.






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






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






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






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






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






29. 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.






30. Restriction or limit placed on a product.






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






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






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






34. A resource that is entered into a system.






35. 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.






36. 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.






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






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






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






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






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






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






43. Energy in motion.






44. 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.'






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






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






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






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






49. 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.






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