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






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






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






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






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






6. The splitting of the nucleus of an atom.






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






8. 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.






9. The formal rules that guide the design process.






10. A resource that is entered into a system.






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






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






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






14. 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.






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






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






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






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






19. Energy in motion.






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






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






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






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






24. The capacity to do work or exert effort.






25. 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.






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






27. 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.






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






29. The capacity to do work or exert effort.






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






31. 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.






32. A popular movement.






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






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






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






36. 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.






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






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






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






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






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






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






43. Someone who starts a business.






44. The basic framework of a system






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






46. 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.'






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






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






49. Stored energy or energy at rest.






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