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






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






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






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






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


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






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






8. 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.






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






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






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






12. 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.






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






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






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






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






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






18. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






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






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






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






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






23. The formal rules that guide the design process.






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






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






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






27. 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.






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






29. A method of obtaining energy from waste products






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






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






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






33. 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.






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






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






36. A resource that is entered into a system.






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






38. 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.






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






40. 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.'






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






42. Creating things through the process of planning.






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






44. 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.






45. The capacity to do work or exert effort.






46. The basic framework of a system






47. 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.






48. Someone who starts a business.






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






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