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 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.






4. 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.






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






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






7. 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.






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






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






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






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






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






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






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






15. 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.






16. The basic framework of a system






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


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






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






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






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






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






23. 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.






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






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






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






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






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






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






30. 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.






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






32. A popular movement.






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






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






35. Someone who starts a business.






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






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






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






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






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






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






43. 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.






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






45. The splitting of the nucleus of an atom.






46. Restriction or limit placed on a product.






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






48. Creating things through the process of planning.






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






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