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






2. 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.






3. A method of obtaining energy from waste products






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






5. Energy in motion.






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






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






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






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






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






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






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






13. The formal rules that guide the design process.






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






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






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






17. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






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






19. 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.






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






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






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






23. Stored energy or energy at rest.






24. 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.






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






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






27. 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.'






28. Creating things through the process of planning.






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






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






31. Restriction or limit placed on a product.






32. The capacity to do work or exert effort.






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






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






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






36. 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.






37. A popular movement.






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






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


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






41. The splitting of the nucleus of an atom.






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






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






44. 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.






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






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






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






48. The basic framework of a system






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






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