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






2. Creating things through the process of planning.






3. Restriction or limit placed on a product.






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






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






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






7. A method of obtaining energy from waste products






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






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






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






11. 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.






12. A popular movement.






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






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






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






16. The formal rules that guide the design process.






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






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






19. 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.






20. 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.






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






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






23. 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.






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






25. Someone who starts a business.






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






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






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






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






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






32. 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.






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






34. The basic framework of a system






35. 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.






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






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






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






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






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






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






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






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


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






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






46. 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.






47. 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.






48. Stored energy or energy at rest.






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






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