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






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






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






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






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






6. The splitting of the nucleus of an atom.






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






8. The capacity to do work or exert effort.






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






10. 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.






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






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






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






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






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






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


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






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






19. A method of obtaining energy from waste products






20. 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.






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






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






23. A resource that is entered into a system.






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






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






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






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






28. 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.






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






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






31. Stored energy or energy at rest.






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






33. Creating things through the process of planning.






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






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






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






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






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






39. Restriction or limit placed on a product.






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






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






42. 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.






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






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






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






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






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






48. 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.'






49. The basic framework of a system






50. 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.
