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 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.






3. 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.






4. The splitting of the nucleus of an atom.






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






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






7. A method of obtaining energy from waste products






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






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






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






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






12. 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.






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






14. 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.'






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






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






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






18. Someone who starts a business.






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






20. The basic framework of a system






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






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






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






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






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






26. Restriction or limit placed on a product.






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






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






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






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






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






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






33. 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.






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






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






36. 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.






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






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






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






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

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






42. 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.






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






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






45. The formal rules that guide the design process.






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






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






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






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






50. A resource that is entered into a system.
