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






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






3. Restriction or limit placed on a product.






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






5. 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.






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






7. 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.






8. The basic framework of a system






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






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






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






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






13. The capacity to do work or exert effort.






14. Stored energy or energy at rest.






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






16. Energy in motion.






17. A popular movement.






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






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






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






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






23. 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.






24. A resource that is entered into a system.






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






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






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






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






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






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






31. The capacity to do work or exert effort.






32. 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.






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






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






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






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






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






38. 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.






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






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






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






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






43. Creating things through the process of planning.






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






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






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






47. The formal rules that guide the design process.






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






49. Someone who starts a business.






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