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. The splitting of the nucleus of an atom.






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






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






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






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






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






8. Energy in motion.






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






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






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






12. 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.






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






14. Creating things through the process of planning.






15. The capacity to do work or exert effort.






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






17. 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.






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






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






20. Someone who starts a business.






21. Stored energy or energy at rest.






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






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






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






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






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






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






28. Restriction or limit placed on a product.






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






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






31. 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.






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






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






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






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






36. 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.'






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






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






39. The formal rules that guide the design process.






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


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






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






43. 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.






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






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






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






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






48. A resource that is entered into a system.






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






50. A method of obtaining energy from waste products
