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






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






3. The capacity to do work or exert effort.






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






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






6. Someone who starts a business.






7. Energy in motion.






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






9. Creating things through the process of planning.






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






12. 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.






13. The basic framework of a system






14. 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.






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






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






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






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






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






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






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






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






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






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






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






26. Restriction or limit placed on a product.






27. 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.






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






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






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






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






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


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






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






35. Stored energy or energy at rest.






36. 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.






37. The splitting of the nucleus of an atom.






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






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






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






41. 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.'






42. 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.






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






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






45. The capacity to do work or exert effort.






46. A resource that is entered into a system.






47. A popular movement.






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






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






50. 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.
