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. 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.






2. 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.'






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






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






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






6. A popular movement.






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






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






9. 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.






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






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






12. The splitting of the nucleus of an atom.






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






14. 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.






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


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






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






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






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






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






21. A resource that is entered into a system.






22. 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.






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






24. A method of obtaining energy from waste products






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






26. The capacity to do work or exert effort.






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






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






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






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






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






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






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






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






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






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






37. 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.






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






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






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






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






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






43. Someone who starts a business.






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






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






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






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






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






49. 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.






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