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 capacity to do work or exert effort.






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






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






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






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






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






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






8. 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.






9. 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.






10. The basic framework of a system






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






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






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






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






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






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






17. Restriction or limit placed on a product.






18. Stored energy or energy at rest.






19. Creating things through the process of planning.






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






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






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






23. 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.'






24. 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.






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






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






27. A resource that is entered into a system.






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






29. A method of obtaining energy from waste products






30. Energy in motion.






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






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






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






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






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






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






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






38. 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.






39. 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.






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






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






42. The splitting of the nucleus of an atom.






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






44. The formal rules that guide the design process.






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






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






47. Someone who starts a business.






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


49. 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.






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