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 path by which electric current or pulses flow.






2. 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.






3. A popular movement.






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






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






6. The formal rules that guide the design process.






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






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






9. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






10. The capacity to do work or exert effort.






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






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






13. 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.






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






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






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






17. Stored energy or energy at rest.






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






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






20. 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.






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






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






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






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






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






26. 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.'






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






28. Energy in motion.






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






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






31. Restriction or limit placed on a product.






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






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






34. 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.






35. A method of obtaining energy from waste products






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






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






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






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






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






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






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






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






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. A resource that is entered into a system.






46. 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.






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






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






49. 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.






50. The basic framework of a system
