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. 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.






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






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






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






5. A resource that is entered into a system.






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






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






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






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






10. 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.






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






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






13. 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.






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






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






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






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






18. Restriction or limit placed on a product.






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






20. 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.






21. 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.






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






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






24. Someone who starts a business.






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






26. The capacity to do work or exert effort.






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






28. Creating things through the process of planning.






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






30. The formal rules that guide the design process.






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






32. A method of obtaining energy from waste products






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






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






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






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






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






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






39. 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.'






40. The capacity to do work or exert effort.






41. A popular movement.






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






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






45. The splitting of the nucleus of an atom.






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






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






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






49. 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.






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