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






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






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






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






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






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






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






8. 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.






9. The basic framework of a system






10. 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.






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






12. 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.






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






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






15. Restriction or limit placed on a product.






16. 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.






17. 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.






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






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






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






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






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






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






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






25. A popular movement.






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






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






28. Someone who starts a business.






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






30. A method of obtaining energy from waste products






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






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






33. The capacity to do work or exert effort.






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






35. Creating things through the process of planning.






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






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






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






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






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






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






42. The splitting of the nucleus of an atom.






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






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






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






46. The capacity to do work or exert effort.






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






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






49. 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.'






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