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 capacity to do work or exert effort.






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






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






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






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






6. 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.






7. 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.






8. Restriction or limit placed on a product.






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






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






11. 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.






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






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






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






15. The basic framework of a system






16. The formal rules that guide the design process.






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






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






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






20. Energy in motion.






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






22. A resource that is entered into a system.






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






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






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






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






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






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






29. Creating things through the process of planning.






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






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






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






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






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






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






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






37. 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.'






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






39. 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.






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






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






42. 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.






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






44. Someone who starts a business.






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






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






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






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






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






50. A method of obtaining energy from waste products
