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






2. 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.






3. Someone who starts a business.






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






5. A resource that is entered into a system.






6. The basic framework of a system






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






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






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






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






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






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






13. Stored energy or energy at rest.






14. 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.






15. A popular movement.






16. 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.






17. 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.






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






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






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






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






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






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






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






25. The formal rules that guide the design process.






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






27. A method of obtaining energy from waste products






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






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






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






31. 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.






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






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






34. The splitting of the nucleus of an atom.






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






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






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






38. 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.






39. Energy in motion.






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






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






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






43. The capacity to do work or exert effort.






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






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


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






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






48. 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.






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






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