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






2. The capacity to do work or exert effort.






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


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






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






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






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






8. A method of obtaining energy from waste products






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






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






11. A popular movement.






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






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






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






15. 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.






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






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






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






19. 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.






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






21. 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.'






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






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






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






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






26. The use of pressurized liquid or gasses to control and transmit power.






27. A resource that is entered into a system.






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






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






30. The splitting of the nucleus of an atom.






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






32. The formal rules that guide the design process.






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






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






35. The basic framework of a system






36. Restriction or limit placed on a product.






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






38. 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.






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






40. 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.






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






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






43. The capacity to do work or exert effort.






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






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






46. Energy in motion.






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






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






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






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