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






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






3. A method of obtaining energy from waste products






4. The basic framework of a system






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






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






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






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






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






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






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






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






13. The splitting of the nucleus of an atom.






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






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






16. 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.






17. Creating things through the process of planning.






18. 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.






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






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






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






22. The capacity to do work or exert effort.






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






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


25. 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.






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






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






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






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






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






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






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






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






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






35. 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.






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






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






38. Someone who starts a business.






39. 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.






40. Stored energy or energy at rest.






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






42. A resource that is entered into a system.






43. The formal rules that guide the design process.






44. 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.






45. A popular movement.






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






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






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






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






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