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. Standards that a product must meet to be accepted.






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






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






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


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






6. Restriction or limit placed on a product.






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






8. The basic framework of a system






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






10. 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.






11. 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.






12. Energy in motion.






13. Stored energy or energy at rest.






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






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






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






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






18. 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.






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






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






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






22. 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.'






23. 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.






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






25. A resource that is entered into a system.






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






27. A popular movement.






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






29. The capacity to do work or exert effort.






30. 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.






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






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






33. 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.






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






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






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






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






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






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






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






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






42. A method of obtaining energy from waste products






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






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






45. 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.






46. The formal rules that guide the design process.






47. 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.






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






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






50. Someone who starts a business.
