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. Someone who starts a business.






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






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






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






5. 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.






6. The capacity to do work or exert effort.






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






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






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






11. 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.






12. 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.






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






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






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






16. Creating things through the process of planning.






17. 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.






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






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






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






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






22. Stored energy or energy at rest.






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






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






25. 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.






26. A popular movement.






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






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






29. A method of obtaining energy from waste products






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






31. The formal rules that guide the design process.






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






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






34. Restriction or limit placed on a product.






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






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






37. A resource that is entered into a system.






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






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






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






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






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






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






44. 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.






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






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






47. 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.'






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

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






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