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






2. 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.'






3. 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.






4. The splitting of the nucleus of an atom.






5. Energy in motion.






6. Restriction or limit placed on a product.






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






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






9. A resource that is entered into a system.






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






11. 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.






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






13. Creating things through the process of planning.






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. 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.






16. A popular movement.






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






18. The capacity to do work or exert effort.






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






20. 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.






21. 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.






22. Someone who starts a business.






23. 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.






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






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






26. A method of obtaining energy from waste products






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






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






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






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






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






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


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






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






35. The basic framework of a system






36. 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.






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






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






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






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






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






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






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






44. Stored energy or energy at rest.






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






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






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






48. 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.






49. 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.






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