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 circuit in which electricity flows along more than one path.






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






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






5. The capacity to do work or exert effort.






6. Restriction or limit placed on a product.






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






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






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






10. A resource that is entered into a system.






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






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






13. The unlawful acquisition of some one's personal information for use without their consent.






14. 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.






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






16. Creating things through the process of planning.






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






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






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






20. Energy in motion.






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






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






23. The basic framework of a system






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






25. 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.






26. 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.






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






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






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






30. 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.






31. Someone who starts a business.






32. 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.






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






34. 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.






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






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






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






38. The capacity to do work or exert effort.






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






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






41. Stored energy or energy at rest.






42. The splitting of the nucleus of an atom.






43. 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.






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






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






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






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






48. 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.






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






50. 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.'
