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






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






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


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






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






6. 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.






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






8. The capacity to do work or exert effort.






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






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






11. The formal rules that guide the design process.






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






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






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






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






16. 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.'






17. The capacity to do work or exert effort.






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






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






20. A method of obtaining energy from waste products






21. 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.






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






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






24. 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.






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






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






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






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






29. The splitting of the nucleus of an atom.






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






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






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






33. Restriction or limit placed on a product.






34. 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.






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






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






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






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






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






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






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






42. Energy in motion.






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






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






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






47. Someone who starts a business.






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






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






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