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






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






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






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






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






6. The formal rules that guide the design process.






7. Restriction or limit placed on a product.






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






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






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






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






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






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






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






15. The splitting of the nucleus of an atom.






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. Studying the effects of a given technology to determine its impact.






18. 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.






19. 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.






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






21. The basic framework of a system






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






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






24. The capacity to do work or exert effort.






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






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






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






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






29. Energy in motion.






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






31. 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.






32. Standards that a product must meet to be accepted.






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






34. A popular movement.






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






36. Someone who starts a business.






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






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






39. 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.






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






41. 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.






42. 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.






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






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






45. 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.






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






47. The capacity to do work or exert effort.






48. 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.'






49. Stored energy or energy at rest.






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