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. Trade of products and services on a global scale.






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






3. The capacity to do work or exert effort.






4. Creating things through the process of planning.






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






6. 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.






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






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






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






10. 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.






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


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






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






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






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






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






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






18. A popular movement.






19. The splitting of the nucleus of an atom.






20. 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.






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






22. A resource that is entered into a system.






23. The capacity to do work or exert effort.






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






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






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






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






28. 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.






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






30. Energy in motion.






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






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






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






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






36. 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.






37. The basic framework of a system






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






39. Stored energy or energy at rest.






40. 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.






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






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






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






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






45. Someone who starts a business.






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






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






48. The use of 3D CAD drawings to create real models of a product within a sort of time.






49. 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.






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