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 money a business makes after all expenses have been paid






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






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






4. 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.






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






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






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






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






9. 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.






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






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






12. 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.






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






14. Someone who starts a business.






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






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






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






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






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






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






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






23. Restriction or limit placed on a product.






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






25. The splitting of the nucleus of an atom.






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






27. A resource that is entered into a system.






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






29. 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.






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

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






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






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






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






35. Creating things through the process of planning.






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






37. 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.






38. 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.'






39. The formal rules that guide the design process.






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






41. Energy in motion.






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






43. The basic framework of a system






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






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






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






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






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






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






50. 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.
