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






2. 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.






3. 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.






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






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






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






7. Restriction or limit placed on a product.






8. A resource that is entered into a system.






9. Someone who starts a business.






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






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






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






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






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






15. The capacity to do work or exert effort.






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






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






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






19. 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.






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






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






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






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






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






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






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






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






28. A popular movement.






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






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






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






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






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






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






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






36. 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.






37. 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.






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






39. The capacity to do work or exert effort.






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






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






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


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






44. Stored energy or energy at rest.






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






46. The formal rules that guide the design process.






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






48. 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.'






49. Energy in motion.






50. 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.
