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






2. Stored energy or energy at rest.






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






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






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






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






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






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


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






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






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






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






14. The capacity to do work or exert effort.






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






16. The capacity to do work or exert effort.






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






18. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






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






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






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






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






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






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






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






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






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






28. 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.






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






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






31. Restriction or limit placed on a product.






32. 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.






33. 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.






34. Creating things through the process of planning.






35. 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.






36. 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.






37. The basic framework of a system






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






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






40. Someone who starts a business.






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






42. Energy in motion.






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






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






45. 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.'






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






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






48. 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.






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






50. The splitting of the nucleus of an atom.
