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 path by which electric current or pulses flow.






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






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






4. The capacity to do work or exert effort.






5. 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.






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






7. The basic framework of a system






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






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






10. The capacity to do work or exert effort.






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






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






13. 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.






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






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






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






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






18. Energy in motion.






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






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






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






22. Stored energy or energy at rest.






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






24. 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.'






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






26. 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.






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






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






29. Creating things through the process of planning.






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






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






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






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






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






35. The splitting of the nucleus of an atom.






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






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






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






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






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






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






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






43. A method of obtaining energy from waste products






44. 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.






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






46. 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.






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. Trade of products and services on a global scale.






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






50. A resource that is entered into a system.
