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






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






3. A popular movement.






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






5. 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.






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






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






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






11. The basic framework of a system






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






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






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






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






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






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






19. 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.'






20. 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.






21. Creating things through the process of planning.






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






23. 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.






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






25. 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.






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






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






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






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






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






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






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






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






34. 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.






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






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






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






38. A method of obtaining energy from waste products






39. 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.






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






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






42. The formal rules that guide the design process.






43. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






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


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






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






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






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






49. A resource that is entered into a system.






50. 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.
