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 imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






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






3. Creating things through the process of planning.






4. 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.






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






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






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






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






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






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






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






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






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






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


15. Restriction or limit placed on a product.






16. A device that orbits the Earth and receives messages from one location and transmits them to another.






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






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






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






20. The capacity to do work or exert effort.






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






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






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






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






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






26. 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.






27. A method of obtaining energy from waste products






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






29. 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.






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






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






32. A resource that is entered into a system.






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






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






35. 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.






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






37. A popular movement.






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






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






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






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






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






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






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






45. 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.'






46. Stored energy or energy at rest.






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






48. 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.






49. 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.






50. The capacity to do work or exert effort.
