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 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.






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






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






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






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






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






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






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






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






10. Creating things through the process of planning.






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






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






13. 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.






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






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






16. The capacity to do work or exert effort.






17. The splitting of the nucleus of an atom.






18. 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.'






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






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






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






22. The formal rules that guide the design process.






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






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






25. 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.






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






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






28. Restriction or limit placed on a product.






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






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






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






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






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






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






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






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






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






38. 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.






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






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






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






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






43. The basic framework of a system






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






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


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






47. 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.






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






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






50. 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.
