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 money a business makes after all expenses have been paid






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






3. The capacity to do work or exert effort.






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






5. 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.






6. 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.






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






8. A method of obtaining energy from waste products






9. Restriction or limit placed on a product.






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






11. Creating things through the process of planning.






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






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






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






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


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






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






18. Energy in motion.






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






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






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






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






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






24. 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.






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






26. 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.'






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






28. A popular movement.






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






30. 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.






31. Someone who starts a business.






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






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






34. 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.






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






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






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






38. A resource that is entered into a system.






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






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 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.






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






43. The basic framework of a system






44. The formal rules that guide the design process.






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






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






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






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






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






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