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 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.






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






3. 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.






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






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






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






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






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






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






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






11. The splitting of the nucleus of an atom.






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






13. 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.






14. A popular movement.






15. Creating things through the process of planning.






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






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






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






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


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






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






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






23. The capacity to do work or exert effort.






24. 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.






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






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






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






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






29. Stored energy or energy at rest.






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






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






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






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






34. 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.'






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






36. The capacity to do work or exert effort.






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






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






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






40. 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.






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






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






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






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






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






46. 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.






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






48. 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.






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






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