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 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.






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






3. A popular movement.






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






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






6. The formal rules that guide the design process.






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






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






9. A method of obtaining energy from waste products






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






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






12. 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.






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






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






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






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






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






18. Creating things through the process of planning.






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






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






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






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






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






24. The capacity to do work or exert effort.






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






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






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






28. Someone who starts a business.






29. Stored energy or energy at rest.






30. 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.






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






32. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






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






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






35. Energy in motion.






36. The basic framework of a system






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

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






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






40. The splitting of the nucleus of an atom.






41. The capacity to do work or exert effort.






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






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






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






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






46. A resource that is entered into a system.






47. 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.'






48. 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.






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






50. 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.
