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






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






3. 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.






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






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






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






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






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






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






10. A resource that is entered into a system.






11. The capacity to do work or exert effort.






12. The basic framework of a system






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






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






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






16. 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.






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


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






19. A method of obtaining energy from waste products






20. The splitting of the nucleus of an atom.






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






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






23. 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.






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






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






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






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






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






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. 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.






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






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






33. Someone who starts a business.






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






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






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






37. The capacity to do work or exert effort.






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






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






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






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






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






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






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






45. 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.






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






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






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






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






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.
