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 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.






2. 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.






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






4. 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.






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






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






7. 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.






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






9. The capacity to do work or exert effort.






10. 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.






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






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






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






14. 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.






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






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






17. 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.






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


19. 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.






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






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






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






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






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






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






26. Restriction or limit placed on a product.






27. A resource that is entered into a system.






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






29. Stored energy or energy at rest.






30. Energy in motion.






31. The formal rules that guide the design process.






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






33. 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.






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






35. A popular movement.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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