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






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






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






4. 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.






5. 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.






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






7. The capacity to do work or exert effort.






8. 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.






9. 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.






10. The splitting of the nucleus of an atom.






11. 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.






12. 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.






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






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






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






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






17. A method of obtaining energy from waste products






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






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






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






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






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






23. 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.






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






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






26. Restriction or limit placed on a product.






27. A popular movement.






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






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






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






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






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






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






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






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






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






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






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






39. Stored energy or energy at rest.






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






41. Energy in motion.






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






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






44. 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.






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






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






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


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






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






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