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 capacity to do work or exert effort.






2. 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.






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






4. 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.






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






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






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






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






9. The basic framework of a system






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






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






12. A method of obtaining energy from waste products






13. Energy in motion.






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






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






16. 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.'






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






18. The formal rules that guide the design process.






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






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






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






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






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






24. 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.






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






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






27. Restriction or limit placed on a product.






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






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






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






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






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






33. Someone who starts a business.






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






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






36. 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.






37. The capacity to do work or exert effort.






38. 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.






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






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






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






42. A resource that is entered into a system.






43. Creating things through the process of planning.






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

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






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






47. 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.






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






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