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






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






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






4. 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.






5. The basic framework of a system






6. A resource that is entered into a system.






7. Someone who starts a business.






8. 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.'






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






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






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






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






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






14. 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.






15. Energy in motion.






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






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






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






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






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






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


22. The formal rules that guide the design process.






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






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






25. Stored energy or energy at rest.






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






27. 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.






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






29. A popular movement.






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






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






32. 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.






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






34. The capacity to do work or exert effort.






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






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






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






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






39. 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.






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






41. The splitting of the nucleus of an atom.






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






43. Restriction or limit placed on a product.






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






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






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






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






48. 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.






49. 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.






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