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






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






3. 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.






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






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






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






7. 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.






8. Stored energy or energy at rest.






9. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






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






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






12. The capacity to do work or exert effort.






13. 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.'






14. Restriction or limit placed on a product.






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






16. 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.






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






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






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






20. 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.






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






22. The basic framework of a system






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






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






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






26. Energy in motion.






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






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






29. A method of obtaining energy from waste products






30. Creating things through the process of planning.






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






32. 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.






33. 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.






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






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






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






37. The formal rules that guide the design process.






38. Someone who starts a business.






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






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






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






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






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






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






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






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


47. 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.






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






49. 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.






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