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






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






3. 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.






4. 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.






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






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






7. The capacity to do work or exert effort.






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






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






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






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






12. 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.






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






14. A method of obtaining energy from waste products






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






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






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






18. Stored energy or energy at rest.






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






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






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






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






23. 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.






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






25. The basic framework of a system






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






28. Creating things through the process of planning.






29. 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.'






30. A popular movement.






31. 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.






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






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






34. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






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






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






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






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






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






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






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






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






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






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






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






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






47. 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.






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






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






50. The capacity to do work or exert effort.
