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






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






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






4. Someone who starts a business.






5. Restriction or limit placed on a product.






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






7. 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.






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. A method of obtaining energy from waste products






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






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






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






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






14. The capacity to do work or exert effort.






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






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






17. 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.






18. The basic framework of a system






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






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






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






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






23. 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.






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






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. Standards that a product must meet to be accepted.






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






28. 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.






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






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






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


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






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






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






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






36. The capacity to do work or exert effort.






37. 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.






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






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






40. 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.






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






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






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






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






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






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






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






48. The splitting of the nucleus of an atom.






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






50. Energy in motion.
