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






2. 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.






3. 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.






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






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






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






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






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






9. Someone who starts a business.






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






11. The capacity to do work or exert effort.






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






13. The formal rules that guide the design process.






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






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






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






17. 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.






18. A method of obtaining energy from waste products






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






20. A resource that is entered into a system.






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






22. The capacity to do work or exert effort.






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






24. Stored energy or energy at rest.






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






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






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






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






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






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






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






32. The basic framework of a system






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 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.






35. Restriction or limit placed on a product.






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






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






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






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






40. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






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






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






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






44. 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.






45. 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.






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






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






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






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






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