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. Restriction or limit placed on a product.






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






3. The capacity to do work or exert effort.






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






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






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






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






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






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






10. 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.






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


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






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






14. 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.






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






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






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






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






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






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






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






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






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






24. The capacity to do work or exert effort.






25. Energy in motion.






26. 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.






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






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






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






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






31. 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.






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






33. Creating things through the process of planning.






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






35. 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.






36. 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.'






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






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






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






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






41. 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.






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






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






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






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






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






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






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






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






50. A method of obtaining energy from waste products
