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






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






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






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






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






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






7. Restriction or limit placed on a product.






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






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






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






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






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






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






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






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






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






17. In a computer - the primary circuit board to which all internal componnets are connected either directly or indirectly.






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






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






20. A resource that is entered into a system.






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






23. 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.






24. 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.






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






26. 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.






27. 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.






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






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






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






32. Someone who starts a business.






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






34. The splitting of the nucleus of an atom.






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






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






37. Stored energy or energy at rest.






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






39. The capacity to do work or exert effort.






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






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






42. A popular movement.






43. Energy in motion.






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






45. 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.






46. The formal rules that guide the design process.






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






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






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 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.
