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






3. 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.'






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






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






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






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






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






9. The splitting of the nucleus of an atom.






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






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






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






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






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






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






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






17. 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.






18. 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.






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






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






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






22. 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.






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






24. Energy in motion.






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






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






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






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






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






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






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






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






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






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






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






36. The basic framework of a system






37. 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.






38. A method of obtaining energy from waste products






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






40. The formal rules that guide the design process.






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






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


43. A popular movement.






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






45. A resource that is entered into a system.






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






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






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






50. 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.
