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 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.






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






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






4. Stored energy or energy at rest.






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






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






7. A method of obtaining energy from waste products






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






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






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






11. The capacity to do work or exert effort.






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






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






14. The splitting of the nucleus of an atom.






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






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






17. 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.






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






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






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






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






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






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






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






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






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






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






28. The basic framework of a system






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






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






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






32. A resource that is entered into a system.






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






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






35. 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.'






36. A popular movement.






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






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






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






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






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


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






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






44. 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.






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






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






47. The formal rules that guide the design process.






48. 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.






49. Someone who starts a business.






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