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. 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.






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






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






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






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






7. A method of obtaining energy from waste products






8. The formal rules that guide the design process.






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






10. Restriction or limit placed on a product.






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






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






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






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






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






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






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






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






19. Energy in motion.






20. 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.






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






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






23. 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.






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






25. The capacity to do work or exert effort.






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






27. Current flow in which electrons move in only one direction.






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






29. 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.'






30. 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.






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






32. Stored energy or energy at rest.






33. 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.






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






35. Creating things through the process of planning.






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






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






38. The splitting of the nucleus of an atom.






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






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






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






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






43. The capacity to do work or exert effort.






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






45. 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.






46. The basic framework of a system






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






48. 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.






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






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