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






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






3. A resource that is entered into a system.






4. Energy in motion.






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






6. A method of obtaining energy from waste products






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






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






9. 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.






10. 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.






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






12. The capacity to do work or exert effort.






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






14. Stored energy or energy at rest.






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






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






17. The basic framework of a system






18. 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.






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






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






21. 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.






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






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






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


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






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






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






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






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






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






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






32. The splitting of the nucleus of an atom.






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






34. The formal rules that guide the design process.






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






36. Restriction or limit placed on a product.






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






38. 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.






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






40. 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.'






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






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






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






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






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






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






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






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






49. A popular movement.






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