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 popular movement.






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






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






4. Stored energy or energy at rest.






5. 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.






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






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






8. 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.






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






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






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






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






13. 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.






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






15. 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.






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






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






18. The capacity to do work or exert effort.






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






20. 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.'






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






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






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






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






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






26. Someone who starts a business.






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






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






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


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






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






32. 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.






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






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






35. 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.






36. The formal rules that guide the design process.






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






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






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






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






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






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






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






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






45. Energy in motion.






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






47. 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.






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






49. Restriction or limit placed on a product.






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