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. 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.






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






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






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






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






6. 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.






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






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






9. Someone who starts a business.






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






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






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






13. 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.






14. A resource that is entered into a system.






15. The capacity to do work or exert effort.






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






17. Restriction or limit placed on a product.






18. 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.






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






20. 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.






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






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






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






24. The formal rules that guide the design process.






25. The basic framework of a system






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






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






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






29. Stored energy or energy at rest.






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






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






32. 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.






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






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






35. 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.






36. Creating things through the process of planning.






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






38. A method of obtaining energy from waste products






39. 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.'






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






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






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






43. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






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






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






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






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






48. The splitting of the nucleus of an atom.






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






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